Thank you for your suggestion Mika, as a general rule I totally agree
with you and I do not mess with kernel default parameters, but I
remember "pcie_aspm=off" was necessary at the time I set up the
system. Probably a kernel or a BIOS update makes it unnecessary today.

I see it removes these messages from my logs but I trust you when you
say they have not an impact on functionality:
