Kernel pci error - AER: Multiple Corrected error received

1

I don’t know if this is the right topic, please let me know if I should open a new one.
I noticed these kernel errors (in both bootlog and val/log/messages) in my logs after last core upgrade (core 178 to be precise) and I have no idea what causes them: pcieport 0000:00:1c.2: AER: Multiple Corrected error received: 0000:02:00.0
BUT! I know how to stop them: by stopping WLANAP and starting it back: all below messages disappear

cat /var/log/bootlog | grep pci - first place where the message pcieport 0000:00:1c.2: AER: Multiple Corrected error received: 0000:02:00.0 ever appear

Searching on the AER: Multiple Corrected error received message it is coming from the hardware although the message has been delivered by the kernel.

Basically the message is saying that the hardware involved found some errors but that it corrected them and that this had happened multiple times.

I found a kernel bugzilla entry on this covering the time period of 2018 to 2023 which has been closed by the kernel devs in May this year and the following is mentioned in that.

PCIe Correctable Errors have already been corrected by hardware and there is no functional impact. Generally they are caused by things like checksum errors that are probably related to signal integrity issues. Clean and reseat the device, etc. All the kernel can do is log these.

So based on the above kernel feedback I would try removing and re-inserting the involved card, maybe cleaning up the contacts beforehand.

Most of the activity in the kernel bug was to reduce the amount of logging that the kernel does for messages about errors that have been fixed as in the earlier parts of the bug people were getting their logs swamped with messages.

From your logs, I would expect the involved card to be your wireless card on blue.
You can always run

lspci | grep 00:1c.2
lspci | grep 02:00.0

which will give you the info on what the card with that pci number is.

The AER message is coming from 00:1c.2 but it seems to be reporting on 02:00.0 so worth checking what both those pci numbers are. Probably the second number is the one of interest but that is just my guess.

Hi Adolf,
Spot on!
I removed the WiFi card and no more errors - none on boot, none in var/log/mesages!

I will clean it up and reinsert it later!
Thank you for the quick response and excellent analyze on the messages thrown by Kernel!

H&M

Late edit: after cleaning & putting the WiFi card back in the errors are displayed again.
I also noticed that /etc/rc.d/rc3.d/S18hostapd is genereting this BOOT message prior to the AER errors above

Line 21: DEPRECATED: 'dump_file' configuration variable is not used anymore
blue0: interface state UNINITIALIZED->COUNTRY_UPDATE

After restarting hostapd I see this:

Starting hostapd...
Line 21: DEPRECATED: 'dump_file' configuration variable is not used anymore
blue0: interface state UNINITIALIZED->COUNTRY_UPDATE
blue0: interface state COUNTRY_UPDATE->HT_SCAN

and no more errors.
Will play a bit with country code to see if that is the cause!

Anyway, I know that WiFi card causes the problems, and I will buy a new one …
Thanks!
