I've been getting a similar problem on a Leopard GP73-8RE laptop from
MSI, on Ubuntu 20.04 as well as 19.10 and 18.04.
This is the message that spammed in my system journal, causing it to
inflate very rapidly to ludicrous proportions:
22:36:51 kernel: alx 0000:03:00.0: AER: [ 7] BadDLLP
22:36:51 kernel: alx 0000:03:00.0: AER: device [1969:e0a1] error
status/mask=00000080/00002000
22:36:51 kernel: alx 0000:03:00.0: AER: PCIe Bus Error: severity=Corrected,
type=Data Link Layer, (Receiver ID)
I tried the following kernel parameters:
-`pci=nomsi`: this also disabls removable devices... not an option.
-`pci=noaer` : disables advanced error reporting without fixing the
errors themselves. It works insofar as it suppresses the message flood.
However, this is akin to "shooting the messenger": it also prevents
troubleshooting other, potentially more serious, errors that won't be
reported as well. Plus, letting errors occur continuously might not be
the optimal solution, even though these errors are apparently getting
corrected.
-`pci=nommconf`: this gets rid of the errors, and so far hasn't had any
undesirable side effect. I'll report back if I notice any.
Someone on reddit has also suggested `pcie_aspm=off` :

But I haven't tried it myself.
