[ubuntu] PCIe Bus Error 1c.5 Ubuntu 20.04 LTS

 
I’ve done a fair bit of searching and tried a few fixes, but I am yet to find a solution.

  • ASUS K501U Laptop
  • Intel Core i5 (6th Gen) 6200U / 2.3 GHz Max Turbo Speed 2.8 GHz Processor
  • 8GB RAM
  • 1TB HDD
  • 1920 x 1080 Resolution
  • NVIDIA GeForce GTX 950M 2GB GDDR3 Graphics (Yes, it is “optimus”)
  • Ubuntu 20.04.1 LTS (Installed 07/08/2020 – Dual Boot with Windows 10)

I noticed my /var/logs/ folder was 155GB :O so I watch tail’d it:

Code:

watch tail /var/log/syslog


I was getting the following error at least once every second:

Code:

pcieport 0000:00:1c.5: AER: Corrected error received: 0000:00:1c.5
pcieport 0000:00:1c.5: AER: PCIe Bus Error: severity=Corrected, type+physical Layer, (Receiver ID)
pcieport 0000:00:1c.5: AER: device [8086:9d15] error status/mask=00000001/00002000
pcieport 0000:00:1c.5: AER: [ 0] RxErr


My NVIDIA driver is up to date, and as far as I can tell is working perfectly, I’ve got minecraft running with shaders, etc, and have confirmed my PC is utilising the GPU and use PRIME for switching (not that I ever do):

Code:

nvidia-driver-440


Other than my /var/logs/ folder filling up rapidly, I’m having little issues (touch wood), the only one being once or twice I have encountered a black screen on boot displaying the error over and over.

I’ve tried editing the grub which has’t helped either, and I’m under the impression that noaer and nomsi only “silence” the error?.

Code:

sudo gedit /etc/default/grub


Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
&
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"


I’ve read about using the following to disable the PCIe Active State Power Management which sounds like it could be related to my issue, but I don’t want to keep messing with my grub without really knowing what I’m doing and just following different solutions online hoping something works.

Code:

pcie_aspm=off
or
pcie_aspm=force


Let me know if you need any more information, I’ve tried my best to put together what I can.

Hoping for some results soon!

Regards,
