My log has been filling up with errors, and it seems to be stemming from my root PCIe port (my NIC is downstream on this one). So, when i download anything on my Windows 11 VM, everything bogs down when I'm connected remotely. Unusably slow...

Problems just started in the past week or so (hard to pinpoint as things seem fine when there isn't something downloading). Trying to figure out if it's chip noise, needing to update the BIOS, failing PSU, failing motherboard, etc.). Any help would be awesome! Not sure if the problems were there before or not (again, because things seem fine when there isn't a download going), but I did just update Unraid about 6 days ago. Didn't notice anything before that.

Currently have Unraid 7.1.4 installed.

I'm just trying to figure out what to fix... I'm hoping it isn't a motherboard issue. I've re-seated PCI slots, checked my power connections, and I'm still having issues. I think the NIC, GPU, and a few other things share the root port that is throwing errors, so the errors (which are all being "corrected by hardware") are throttling everything with interrupts. Not sure what to do besides replacing the motherboard...

Try this first:

Unfortunately, that didn’t work…. Ran cat /proc/codling to confirm it was in there too.

Unless I did something wrong (honestly thats the first time I’ve edited my config).

Try this instead, but this will only suppress the errors, if it works:

Errors are still reporting, but the bottlenecking isn't happening anymore!

Not sure if it was just the error suppression or the combination of that with the ASPM getting turned off, but all good now.

With the errors still being there, is it something to be worried about, or is it just a hardware quirk for ASUS motherboards?

Most of the time they are not a real problem, but it would be better to really get rid of them. Swapping PCIe slots can sometimes help; also, look for a BIOS update.

Yeah, about to be moving, so once I get everything set back up at the new place (set up and stable), I'll check for an update.

The port that's throwing the error is not a slot that I can just swap from (I don't think)... I traced it all the way through and all of the components downstream are built in to the motherboard (not external devices seated in a PCIe slot). Here is the result of
