Manuel, does this problem still occur?  I can't see what the problem is
in your dmesg logs.  Your logs contain 'PCI: Using host bridge windows
from ACPI; if necessary, use "pci=nocrs" and report a bug', booting with
"pci=use_crs" shouldn't make a difference on your machine.

If this is still a problem, can you attach the complete dmesg logs both
with and without "pci=use_crs"?

Thanks!
