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"?
