Patch for the AER message spew

Description Lev Lybin 2016-01-31 13:40:09 UTC 
Reproduced not always, only after rebooting. If did shut down laptop, and run again - no problem, but if do reboot - can see errors again.

Marc Merlin 4.4.1 dmesg

Marc Merlin reported what appears to be the same problem here:

  http://lkml.kernel.org/r/20160213215736.GA1002@merlins.org

I'm attaching the dmesg log he captured.

I suspect "pci=noaer" is a workaround (it disables AER completely).

Comment 3 Sebastiaan la Fleur 2016-08-12 08:41:18 UTC 
Seems I get a very similar issue on my new Thinkpad P50 with the Arch linux kernel. No clue yet as to why, but I see two direct similarities:

- Intel i7 6700HQ
- Nvidia Quadro M1000M

I receive the same error message at boot everytime. Both with a new Arch linux install as well as the install image on kernel 4.6.1

I will be posting the complete dmesg log, however, a single difference is in the error message I receive. My AER corrected id=00e4.
Comment 4 Sebastiaan la Fleur 2016-08-12 08:48:54 UTC 
Some more resources I found when googling the error:

https://bugzilla.kernel.org/show_bug.cgi?id=109691
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173

The system with the issues has an Intel wifi chip but a realtek PCIe card reader. Will check to see if the connected PCIe device causing the errors is the card reader.
Comment 5 Sebastiaan la Fleur 2016-08-12 15:51:51 UTC 
Disregard my previous messages. It seems it was a driver issue. After I reinstalled the nvidia and intel drivers, any error messages about AER were gone.

Patch for the AER message spew

Hello Folks,

I have a potential patch ready for the AER message spew problem, but unfortunately, I do not have a system that outputs the same AER errors so I am unable to test it out.

It would really help if anyone could please test this patch and see if it solved the AER message spew.

Thanks,
Naveen Naidu

Thank you and sorry, my laptop is died already :)
Comment 8 geflis 2022-06-27 13:01:04 UTC 
Hi,

Have this bug been further investigated?
Sory to maybe opening this topic back after so long time, but I have same issue on my system and have not found any proper soluton yet.

I am running Ubuntu 20.04.4 Server and have issues with notably Intel Ethernet Controller. 

Strangely enough, I had 2 same systems (one I have fried due to bad wiring) where on one system everything was ok, but the other one (the one I am currently running) I have this message constantly...
