What are these syslog messages?

[Ralf Mardorf]

PS:

"pcie_aspm=off disables much of PCIe power management. You might not
care about that on a desktop, but on a laptop it might be important, not
only to limit power consumption, but also keep the heat generation
within manageable limits. The cooling solutions on laptops tend to not
be quite as effective as on desktops and servers, for obvious reasons.

pci=noaer might be a better option, as it turns off just the error
reporting part. The hardware will still follow the default error
correction policy as set by the system firmware (BIOS or UEFI), but the
Correctable PCIe Bus Error messages should no longer be generated." -

Counterargument: Disabling the PCIe Advanced Error Reporting (AER) does
silence all error reporting, not just the spam.
