XPS 9560: Flood of PCIe errors in log

I was having some issues with my wifi card, a common issue with this laptop. I tried the solution mentioned here:

sudo mv /usr/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin /usr/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin.bak

To try and load some different firmware. This works, as evident from the output of dmesg:

# dmesg | grep ath10k_pci

This seemed to fix the wifi issue, so far. However, I'm now getting a bunch of PCIe errors:

At first, I thought it was the wifi card complaining. But lspci shows that [8086:a110] is not the wifi card:

...
...

It's the PCI bridge. So, it seems like it's an unrelated problem, but it only started after fiddling with the wifi issue. Does anyone have any insights about what this could be caused by?

Re: XPS 9560: Flood of PCIe errors in log

Looks familiar to me. In my case the errors came from the M.2 NVMe module - Hynix in my case.
I don't have the XPS 9560 anymore though. Went back to Dell.

Re: XPS 9560: Flood of PCIe errors in log

I also have an XPS 9560 with a 1G Hynix drive, and was getting similar errors. I haven't isolated the cause, but setting 'pci=nommconf' in the kernel options got rid of the errors.
