I have been getting these errors since I started using Unraid. I am not sure if they actually cause harm, but the server recently shut down randomly after I initiated a reformat of a drive.

 

The only two cards I have attached are an Asus IPMI card and a Broadcom LSI 9300-16i.

 

Any suggestions?

AER Errors are usually power/cable connection and/or sleep states.

The PCIe AER driver provides the infrastructure to support PCIe Advanced Error Reporting capability. The PCIe AER driver provides three basic functions: Gathers the comprehensive error information if errors occurred. Reports error to the users.

are they being passed to a vm?

I recommend a grub option to turn of aer...

 

the grub option:
pci=noaer pcie_aspm=off

 

kernel /bzimage
append initrd=/bzroot pci=noaer pcie_aspm=off

Thanks for helping me out.

To be honest I have no idea what you are saying. Is this in English? 😂

 

I am not a Linux guy so I don't know what any of this means. Are you saying I should edit some settings on my Unraid flash drive?

Edit: In the end, I decided to get rid of the LSI 9300-16i because I didn't want to take the risk of using it while not fully understanding what the error messages meant. The following part was my solution to turn off the warnings, but it might not be so wise:

 

OK I think I managed to turn off the warnings eating up the log file.

 

I am not seeing the error anymore, but I also don't know if I should be worried about it. Everything works, but only as far as I can tell.

 

Here is what I did:

 

1. Made a backup of the flash drive
2. I opened the terminal in Unraid and entered: nano /boot/syslinux/syslinux.cfg
3. I entered the pci=noaer pcie_aspm=off on line 9
4. CTRL + X to exit, Y to confirm, and Enter to save.

 

Here is the full syslinux.cfg after the change:
