Random kernel panics on boot. 2.6.38-ARCH

Dilzo · 2011-05-15 12:06:22

For a few days now when i try to boot my pc i will run into a kernel panic almost every time. It might happen once or i might have to reboot a few times before she starts up properly.

I haven't a clue why my computer is doing this and i cant see anything i can interpret in the panic message. I've taken a picture to see if you guys can help.

Thanks.

I've encountered the same problem. No clue how to fix this.

clearloon · 2011-05-15 19:40:31

I'm having this problem too - the error message looks pretty much identical.

I can "fix" it by either downgrading the kernel to kernel26-2.6.38.5-1 or by reducing the number of cores I use from 4 to <=3.

Hmm, thats interesting. Would that mean there is something wrong in the kernel relating to multicore CPU's? Ive got a quad core phenom

Maybe... mine's AMD Phenom(tm) 9650 Quad-Core. I've been searching forums for other distros and not come across it, nor any reports that seemed related...

Dilzo · 2011-05-15 19:45:20

Thats my CPU.....

IceOnly · 2011-05-15 21:03:30

I have the same issue.
But only with an attached usb harddrive.

My CPU: AMD Phenom(tm) II X4 940 Processor stepping 02

I get just that, randomly.

I need to fix so that i can see the whole boot-message somehow (or pehaps kernel panics get's logged?)

It happens right before the deamons starts getting loaded.

It has some mentions of ksoftirq, and scsi_mod.

And it is also happening right where it (udev?) should detect my External USB Disk Drive.

A reset after that, and it instead freezes on detection of the USB2-disk drive, instead of a kernel panic.
And i have to unplug it and it will boot the next time.

This happens sometimes.

My Hardware:

Intel Core i5 2500k (Sandy Bridge) @ 3.4 Ghz.
4 GB 1600Mhz XMP-Profiled Ram
NVIDIA GTX 570.

Though it feels to be something with the usb and the kernel.

SpartanStevo · 2011-05-19 01:51:31

I get these as well.
Randomly, although I think you all's above are happening on boot up?
Mine are all happening randomly while I'm doing stuff.

My Hardware (much less than most above):
Intel Core 2 Duo (2.00 Ghz)
3GB Ram
ATI Radeon

ntness · 2011-05-19 02:03:21

Exact same thing happening here.

AMD Phenom II X4 955 3.2GHz Socket AM3 Quad-Core
4GB (2x2GB) G.SKILL Ripjaws DDR3
Nvidia 8800gt
Latest Kernel + FRESH install

I get this occasionaly to, started a thread in newbie corner, here's the pic I took:

Hardware
AMD Phenom II X4 955 Quad-core
Kernel 2.6.38-ARCH

This only started happening with a USB hard drive attached.

Hold it. That is quite a clue there.

If it is disconnected, does this happen?
What are the chances this drive is being mapped to where grub thinks your real boot disk is located?

I have this too, and as i wrote further up, it is indeed (in my and his it seems) caused by the usb-harddrive.

In my case, i have it mounted through fstab, with ntfs-3g (fuse) and to sdd.

Right at the point where (is it udev?) "recognizes" harddrives, and before the daemons-part of the init starts, this kernel panic happens.
Where i usually see sdd referenced and flashed by, the times it do work.
For sometimes it does, sometimes not, and a quick reboot after the kernel panic instead makes it freeze at the same point (no kernel panic the other time)
Power of, and a new go, and it will most often work again (with the usb drive) until the next random boot-kernel-panic.

(so it is not mounted yet, since it is before the "mounting partitions" part of the init scripts.)

Look further up for as much info as i, as a mere semi-mortal, could asses about it thus far atleast.

I have the same problem with an AMD Phenom II X4 840.

Though, it happens very rarely. and it hasn't happened to me in at least a week.

I think you may be on to something about the USB drives. It only happened to me a few times shortly after I finished installing Arch on this computer, and I was still setting things up. During that time, I still had the USB I used to install Arch plugged in.

jonnybarnes · 2011-05-20 21:22:52

Yeah, just booted up 5 times without the USB HDD plugged in, 5 normal boots.

5 times with USB HDD plugged in, 4 kernel panics.

PReP · 2011-05-20 22:39:49

Perhaps the new kernel/init/something is more picky when it comes to harddrive response?
Just a blind guess, since i know that atleast my usb drive has this irritating spindown after mere seconds of inactivity, causing a delay whenever it has to be accesesed again.
This happens in the drive itself in any os, and is annoying enough.

Don't know if the timeout for when it tries to asses the drives at boot, is much shorter now, thus making this.

But, perhaps not.

prospex · 2011-05-22 06:54:14

I'm having similiar problems. Booting is fine, but plugging in USB devices randomly causes kernel panics. So far it only occurs with usb storage media. Not sure if its amd related, but I have an amd phenom 9750.

Edit. I should add that I don't have any usb storage media plugged in when I boot.

I have the same problem with my Phenom II X4 running Kernel 2.6.38-ARCH. I also have an USB HDD permanently connected.

perbh · 2011-05-25 19:52:57

Do you guys have your usb's mounted via /etc/fstab?
I have never had any such problems (on an assortment of different h/w), but I always wait with the mount until I get to /etc/rc.local - and do the mount there ... something like this:

usb_blkid="..........."
usbdev=$(blkid | grep "$usb_blkid" | cut -d ':' -f 1)
test "x$usbdev" = x || {
  echo ":: mounting $usbdev ..."
  mount -t ntfs-3g -o rw,umask=000,uid=0,gid=0,utf8 $usbdev /media/usb || echo "-- usb-mount failed"
}

... works for me

PReP · 2011-05-26 00:47:39

Well, yeah, i mount it trough fstab, as i wrote further up, since i have it plugged in all the time and that is the simplest way.
I don't run dbus or such either. but Thanks for the tip anyways.

I just found this on the mailing-list (reading on as i post the link) : http://mailman.archlinux.org/pipermail/ … 20410.html

Udev seems to be have been the issue, udev-168-2 should fix that

I've been having the same thing happen to me on a "new" computer I'm setting up. I have some old school AMD 3200 (the old school chip) stuff laying around that I was putting together for a kitchen box. I thought my problems were all hardware related (I have 4 other systems that run fully updated Arch without issue) but now that I'm seeing this thread, I just unplugged the USB CD-Rom drive I had plugged in for install purposes. The only other difference between my 5 systems is its the only one running 32bit Arch so if that gives any other pointers....

PReP · 2011-05-26 02:51:07

Just make sure that:

~ -> pacman -Qs udev
local/udev 168-2 (base)

And then, cross fingers, and be happy and thankful to our hard working maintainers and devs (hopefully)
So far, it seems solved - for me - atleast.

My problem may be different then what everyone else is experiencing, but i had udev 168-2 installed on the system in question and I was still experiencing freezes. I decided to install udev from testing (170*?) and the computer ran all night without any errors. First i've seen it do that since I started having this issue.

clearloon · 2011-05-27 16:58:56

I have udev 168-2 and the issue persists for me. Workarounds for me are either:

1) unplug my external USB drive (not ideal as I use it for back-up)
2) downgrade the number of cores I run from 4 to 3
3) downgrade to kernel 2.6.38.5-1

Currently going with 3)

vinipsmaker · 2011-05-29 01:46:59

I'm having this trouble too.

It happens randomly to me.
Sometimes it happens during boot, when udev starts.
And sometimes it happens when I'm doing some important work.

Up to now, it only happened when I was using a samsung s2 external hd.

My PC is a AMD Phenom II X4 940 Quad-core 4GB RAM.
Latest Kernel

EDIT:
I'm using udev 168-2 and the problem is still happening to me.
