Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Hi all,

Shortly after upgrading from Linux 3.11.6 to 3.12, I started getting kernel panics while playing streaming media (in particular from Youtube and The Daily Show). Here is a camera shot. The crash would not take place immediatly, but perhaps after 15 minutes of streaming. After downgrading to Linux 3.11.6 everything works fine. Therefore, it is clear to me that the issue is related to the Linux 3.12 kernel, but this is all I know.

The fifth-to-last line from the camera shot reads:

[11438.332699] RIP  [<ffffffff8129e160>] __sg_page_iter_start+0x20/0x20

A quick Google search reveals that __sg_page_iter_start is a function inside the scatterlist.h library in the Linux kernel, which apparently deals with memory paging, but my knowledge about this stuff is so poor that the message is almost meaningless. I would greatly appreciate if someone could give me a hint about this.

I did not find anything useful in the journal, but here are the last few journal lines for 2 different crash instances:

In the first journal log, the following line calls my attention:

Nov 15 00:26:02 xps kernel: perf samples too long (2530 > 2500), lowering kernel.perf_event_max_sample_rate to 50100

However, this seems to be a normal occurrence after playing games (https://bbs.archlinux.org/viewtopic.php?id=170471), so I would guess this is not related to the kernel panic.

For reference, here are some hardware specifications of my Dell XPS 13:

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

I've got the same issue, unfortunately little light to shed on the situation as yet.

I've got a Sony Vaio pro 13 which so far as I can tell puts me in much the same place as your Dell - no physical ethernet port.  Google lead me to your post with a seaarch for "linux ax88178_178a kernel panic", so I would guess we've got similar USB ethernet adapters.  Mine is this LevelOne model: http://global.level1.com/Network-Card/U … p-3209.htm but I can only imagine the chipset will show up in a number of places if one were to look hard enough.

Have your issues been confined to periods of high network activity?  I've had panics during activities as mundane as browing Google+ or Reddit, but conversely have had days where I've shifted 200GB off my NAS onto my laptop at near the full 110MB/s line speed of gigabit ethernet without a single issue.

Here's the screen photo from mine when it pops: http://i.imgur.com/NCanPUY.jpg

I'm running Gentoo, and as you can see I've gone as far as grabbing the linux-next git repo and running my system on that.  Your comment has given me a thought though, I'll attempt backing out the changes in drivers/net/usb/ax88179_178a.c that occured between 3.11 and 3.12 and see if it improves anything.  I will report back once I've had some time to test the result.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Hi qupada. Thanks for your response. Yes, I also think this is related to the USB ethernet adapter. I am using this Plugable USB 3.0 model: http://amzn.com/B00AQM8586, which works great for kernel versions older than 3.12. As you already found out, it uses the driver "ax88179_178a," which is very similar to yours.

My kernel panics are quite random. One day my system was able to cope with several hours of fullscreen Youtube, but the next day it crashed while visiting a normal website which required minimal bandwidth (it did have an embedded youtube video, but this is probably unrelated).

I haven't really done much testing, for example to check if the panic also occurs when using wireless (I guess not), but I am sure that this problem was introduced with Linux 3.12. I also tried the newer Linux 3.12.1, to see if the issue had been magically fixed, but no luck, so I have been using version 3.11.6 since then.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Alright, I've found a likely candidate, it mentions dma_sg, which appears in the stack trace on both our systems..  I'm now running yesterdays's linux-next HEAD (3.13.0-rc2-next-20131205), with this patch reverted.

https://git.kernel.org/cgit/linux/kerne … f290d227c8

Too early to say yet, I might take a gander at the USB code later to see if I can figure out what that feature's actually meant to do.  The commit message references testing on ARM so this could be a fun architecture-specific one.

I think for the moment if you want to go back to 3.12, wireless is definitely safe.  Might be a good opportunity to buy yourself a shiny new 11ac router? wink

Interesting! This does look like a good candidate. Apparently this was only tested on an ARM architecture (?). Let's see if your system doesn't crash during the next few days.

Yeah, this is tempting, but I think I'll hold on for a while. Also, for some reason I prefer wired connections. I guess I'm old school smile

(I renamed it with udev to eth0 - the new-style auto-generated name of enp0s20u1 just really wasn't doing it for me)

I'm not sure if the comparatively high number of dropped packets is anything to be alarmed about.  We're only talking 0.02% or there abouts, it's just high compared to a "real" PCIe adapter in my work PC - 17 dropped for 728GB throughput in ~23.5 days.

The most I think I managed under the old crashing behaviour was about 3 days of uptime so I'm not entirely willing to call it fixed just yet.  At least CPU usage doesn't seem to have increased noticably.

One other question I've been pondering is if the number of devices on the network - and related factors such as the quantity of broadcast, multicast and non-IP traffic - have any effect on the issue.  My network (picture below of general layout) has an abundance of RSTP and LLDP frames from the two managed switches.  The WiFi traffic (up to 9 devices on any given day) is split about 50/50 between the main subnet and a VLAN.  Everything but the printer is connected at 1000Mbps.

I've also had another look around for others with the same issue, but yours is the only remotely relevant posting I've found so far.  I might try Freenode's ##linux to see if I can find anyone else with similar hardware.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

I don't think I have any fancy network setup. I just connect a cable from my USB ethernet adapter to the ethernet port on the wall.

About the packet loss rate, this is what Wikipedia has to say about it:

As a rule of thumb derived from day-to-day practical experience, in general with TCP/IP protocols a packet loss below 0.1% (1 lost packet in every 1000 packets) can be tolerated; anything higher will have more or less impact (depending on circumstances) and needs to be addressed.

So, a packet loss rate of 0.02% is probably still OK smile

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

I'm having exactly the same problem (on a Dell XPS 15 Haswell)... I just got the machine so I never tried with kernel 3.11. After a few crashes with kernel 3.12, I decided to try 3.13-rc4, but I got a kernel panic again after a few days...

qupada/vrg: Did you find a solution to this problem? Was the bug reported upstream?

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Hi drinkcat. I'm still working with kernel 3.11.6, but this should be fixed at some point. The patch that qupada found looks promising, and since I haven't heard back from him I'm guessing that it worked. But I don't think a bug report has been filed yet.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

I'm still alive, I promise.  It's just it's summer in my part of the world so less time spent using the computer.  I'm on holiday so the USB adapter's getting less use than normal but it's been working just fine for the last nearly 3 weeks.

Since last time, I've had a 9 day uptime (before the WiFi driver broke and refused to restart the card, even with the somewhat severe action of dropping it from the PCIe bus and rescanning for it), and currently sitting at 7 days 20 hours.

I'm working on a LKML bug report as we speak.  I'll paste a draft before I submit it in case either of you have any comments.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Thanks for your replies.

For some reasons I had panics after a few minutes of traffic only on a vanilla 3.13-rc4, but sometimes it takes days...

I will try again with 3.13-rc5, and the commit reverted.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

FYI, I've had no problem on 3.13-rc5, with the commit reverted, for 7-8 actual days (~8h/day with the adapter plugged). Way more than I've been able to do with 3.12.x or vanilla 3.13-rc*.

It would be good to submit a report quickly to have a chance of getting it fixed in 3.13.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Alright, so it seems like a patch has been included in 3.12.7:
https://git.kernel.org/cgit/linux/kerne … b0f0740aa2

And mainline kernel:
https://git.kernel.org/cgit/linux/kerne … f6de51ec3e

Will test 3.12.7 and let you know.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

That's great news!

I wasn't aware of any of this because, unfortunately, my Dell XPS 13 ultrabook died unexpectedly. One day I rebooted and it never turned on again... Probably a motherboard failure (apparently common with this model). It was only 4 months old, so it should still be covered by the warranty. After the repairs, I think I'll be getting a different laptop...

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

Posted to netdev@vger.kernel.org, I hope I just haven't dawdled for too long and this can make it to 3.13 final.

Hopefully this should be sufficient information, I've linked to this thread too.  I've also mentioned I'm willing to beam one at someone from Amazon, with 2-day shipping to the USA the Pluggable branded adapter is just under NZD$40, which I can easily live with.


===========================================================================================================

USB3 gigabit ethernet adapters with the ASIX AX88179 chipset (LevelOne USB0401-V3, Plugable USB3-E1000, SIIG JU-NE0211-S1 and others) are experiencing kernel panics in usb_hcd_map_urb_for_dma since 3.12.  The issue does not seem to directly correlate with low or high network activity, occurring seemingly at random.  Some panics occurred less than 5 minutes from boot and tens of megabytes of network transfer, while on other occasions it would be stable for multiple days with tens to hundreds of gigabytes of line-rate throughput and several sleep/resume cycles.

Both my Sony Vaio Pro 13 and another user reporting this issue on the Arch forums [1] are Intel-based, my USB controller is an 8086:9c31 (Lynx Point LP), the other is reported as a C210/7 series (unknown PID).  A third with a Haswell Dell XPS has attempted my workaround and reports similar success.

I have a mediocre quality photo of my laptop's screen from one of these panics [2], the call trace - which is similar but not identical between my machine and that of the other user reporting the issue - is as follows:

usb_hcd_map_urb_for_dma
usb_hcd_submit_urb
local_bh_enable_ip
selinux_parse_skb
usb_alloc_urb
__kmalloc
usbnet_start_xmit
usbnet_start_xmit
dev_hard_start_xmit
sch_direct_xmit
dev_queue_xmit
ip_finish_output2
ip_finish_output
ip_output
dst_output
ip_local_out
ip_queue_xmit
tcp_transmit_skb
tcp_write_xmit
__tcp_push_pending_frames
tcp_push
tcp_sendmsg
inet_sendmsg
__sock_sendmsg_nosec
sock_sendmsg
set_restore_sigmask
set_restore_sigmask
fget_light
SYSC_sendto
set_restore_sigmask
SyS_sendto
system_call_fastpath

So far as I can tell, the driver is unaffected as late as 3.11.6, but problematic as of 3.12 (and still affected in 3.13-rc5).  The history of drivers/net/usb/ax88179_178a.c for this time period yields this patch, which at least in my somewhat limited understanding appeared a likely candidate.  I've reverted this on my system - against several linux-next builds from the last 3-4 weeks - and have had no issues with this network controller since.

    USBNET: ax88179_178a: enable tso if usb host supports sg dma

    This patch enables 'can_dma_sg' flag for ax88179_178a device
    if the attached host controller supports building packet from
    discontinuous buffers(DMA SG is possible), so TSO can be enabled
    and skb fragment buffers can be passed to usb stack via urb->sg
    directly.

    With the patch, system CPU utilization decreased ~50% and throughput
    increased by ~10% when doing iperf client test on one ARM A15 dual
    core board.

Unfortunately I have not retained the built kernel from a broken 3.12 build, so the system information below reflects the patched linux-next kernel I am running currently.

I understand this may be a somewhat obscure piece of hardware, I am willing to assist by drop-shipping one to someone from Amazon (or local country equivalent if the price is not extortionate) should it be required.

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

FYI, got my first panic on unpatched 3.12.7, after 2 days of use (~12h in total). After reboot, second panic came within minutes.

Will revert to 3.13-rc8, patch reverted for further testing.

EDIT: Changed my mind, will revert the patch on 3.12.7, to avoid problems with nvidia and bbswitch...

Re: Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

My thread, and another spawned with a suggested fix, from the mailing lists:

http://thread.gmane.org/gmane.linux.net … cus=101541
http://thread.gmane.org/gmane.linux.net … cus=299511

I'm testing with the patch from the second thread, so far so good.
