PCIe Bus Error

Hello,

I bought a new Laptop and installed Arch Linux with the i3 Window Manager. Everytime I shutdown my PC while my wireless interface is up, this message

keyhoi kernel: pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, device [8086:9d15] error status/mask=00000001/00002000 [ 0] Receiver Error		(First)

Re: PCIe Bus Error

Do not post pictures of output, post the actual text.

https://wiki.archlinux.org/index.php/Co … s_and_code

Also, can you elaborate more on this line:

Everytime I shutdown my PC while my wireless interface is up, this message(the red one) is printed till I shutdown my PC manually.

How do you initiate the shutdown and what do you mean by manual shutdown?

Re: PCIe Bus Error

What is the output lspci   ?  In particular what device is at 0000:00:1c.5  ?

Re: PCIe Bus Error

Dunno what it is, except that it's some error reported by hardware and possibly caused by things being powered down.

Just write some scripts which rmmods the WiFi driver at shutdown if you say it helps wink

The problem is I can't enable NetworkManager, because if i do so, the message is printed at boot up till i shutdown the Laptop.

Re: PCIe Bus Error

So it's not just every time you shutdown with the interface up but all the time the interface is up? roll

OK, since it says the errors are already corrected anyway, maybe just disable error reporting wink Try adding pci=noaer to the kernel boot parameters.

Re: PCIe Bus Error

Well, what we learned from your truncated lspci output was that the device that was throwing the error was the root port.  Had you posted that for which I had asked, we would know what devices were on that bus and, perhaps, gained some insight into the root cause.

Personally, I would not be shutting down that way. If I'm not mistaken, that is a "forced shutdown". Try "poweroff" from a prompt or something. (This is probably not the cause of the issue, but just general advice.)

I know, but I have to. The message is printed every 0.1s till I do a forced shutdown.

Re: PCIe Bus Error

The requested info does appear to be in the lspci output.

00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1) (prog-if 00 [Normal decode])
	Flags: bus master, fast devsel, latency 0, IRQ 124
	Bus: primary=00, secondary=03, subordinate=03, sec-latency=0

So attached to the affected root-port is bus 3 (secondary=03). Which is the wireless network device.

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter

This is an interesting problem, and I would wager it is a kernel root-port driver issue or a realtek driver issue (since the root-port is the device flagging the receiver errors, this likely means it is getting PCIe framing errors from the attached realtek device, or the attached PCIe device is going to electrical idle, and the root-port is not properly detecting it.

But something during the reset process may be causing the realtek device to go haywire with an unclean shutdown flow.  Normally Intel hardware reset flows have a watchdog timer that will eventually force a global-reset even if a device is not responding, but you mentioned that reset never occurs and you are forced to issue a cold-reset (holding down power button).   This might indicate that the OS is not even reaching the point of asking for a reset because it is stuck waiting on something else (hence why it could be a kernel root-port related issue with reset under the presence of errors which trigger interrupts).

I would suggest trying the LTS kernel, and seeing if it useable and if there is any reset behavior difference.   I do know that skylake took a long time to be useable in linux, and so I am unsure if the LTS kernel will work for that hardware, but it  will provide some extra data points that may help.

EDIT:  Also check your BIOS settings and see if you have PCIe ASPM enabled.  If so, try disabling it.  If there are separate bios settings for L0s and L1, disable both.

Edit2::  Additionally, make sure you have intel-ucode installed and enabled in your boot loader.  The reset flows are controlled in SunrisePoint by firmware that lives in the PMC (power-management controller).  This gets loaded by BIOS, so also check your laptop vendor for BIOS updates, as there could be fixes available.

Re: PCIe Bus Error

Hi, I'm brand new to Arch but not Linux, so please excuse my ignorance if I've said anything wrong.  I'm trying to install Arch and I've run into the same PCIE bus error on the same port (00:1c.5), but in my case I can't even do anything about it hmm . I've been using KDE Neon till now and used to have the same problem on boot, but I managed to add pci=nomsi to my grub and this made the error not show up on boot.

But I can't seem to do the same from my live USB install of Arch and the error just keeps printing on screen wherever I am so I can't edit files too (not sure if those printed errors will end up saving in the grub file too, besides I am not even sure if the grub file on the Live USB is writable and whether changes will even be saved on the next boot...) . I also dual boot Windows 10.  Any help would be great, I really want to try out Arch. I heard the community is great too. I posted the same problem on Kde forums and no one gives a damn there.

I've also read the replies above, PCIe ASPM doesn't show up on my BIOS. Is it possible to install intel-ucode in the storm of errors being printed on my console? Or is is a fundamental problem with my laptop? I can't remove Windows as I use that for my games and have a ton of stuff there too.

Re: PCIe Bus Error

Please do not necrobump.
Ensure windows fastboot is off, https://www.tenforums.com/tutorials/418 … -10-a.html
If that's settled, please open a new thread, post the actual message and an lspci output.

The "error" is none, there're problems to communicate w/ the PCI device but the call is repeated and the error corrected. (Ie. a "loose contact", works, works not, works…)
