A new Lenovo ThinkPad E480 laptop showed errors like
PCI Bus error severity=Corrected among others. I searched for a solution and added the kernel boot parameter
pci=nomsi permanently. The PCI error is solved, but there appear to be other errors as well. The following is the output of
dmesg -T -l err:

I also had issues with keys of my keyboard that wouldn't react or get locked like the F1 to F12 and the Esc key. Today they functioned correctly but scrolling with two fingers didn't function even though it was set in the settings.
How may I troubleshoot to resolve these issues?
