So like this?
dmesg | grep -i xid

I just ran dmesg and see a number of these type messages:
[269351.243437] pcieport 0000:00:03.0: AER: Multiple Corrected error received: 0000:00:03.0
[269351.243442] pcieport 0000:00:03.0: AER: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
