What are these syslog messages?

[Eyal Lebedinsky]

I am playing with a laptop (Dell XPS 15 9560) that failed for a friend and I inherited it.
I got it to mostly work, and I am now looking for any issues.

I note these errors in syslog, repeating many times.
	kernel: pcieport 0000:00:1d.6: AER: Correctable error message received from 0000:06:00.0
	kernel: pcieport 0000:06:00.0: PCIe Bus Error: severity=Correctable, type=Data Link Layer, (Receiver ID)
	kernel: pcieport 0000:06:00.0:   device [8086:1576] error status/mask=00000080/00002000
	kernel: pcieport 0000:06:00.0:    [ 7] BadDLLP

I think that the device mentioned is related to USB-C. This is the end of lspci:
	06:00.0 PCI bridge: Intel Corporation DSL6340 Thunderbolt 3 Bridge [Alpine Ridge 2C 2015] <<<<<
	07:00.0 PCI bridge: Intel Corporation DSL6340 Thunderbolt 3 Bridge [Alpine Ridge 2C 2015]
	07:01.0 PCI bridge: Intel Corporation DSL6340 Thunderbolt 3 Bridge [Alpine Ridge 2C 2015]
	07:02.0 PCI bridge: Intel Corporation DSL6340 Thunderbolt 3 Bridge [Alpine Ridge 2C 2015]
	3e:00.0 USB controller: Intel Corporation DSL6340 USB 3.1 Controller [Alpine Ridge]
The laptop does not have ethernet so I am using a USB-C NIC.
The above devices only show when the adapter is plugged in.
No errors show when the same adapter is used on another laptop.

My initial question is: what is the complaint about?
It is possible that the machine has a hwr problem, it had some coffee spilled on it.

BTW. I noticed this first when I used clonezilla to save an image of this laptop,
which completed without errors... that is until I looked at the syslog.

It runs ubuntu 24.04 with all updates applied.

TIA
