Hi, I think not. Does booting with "i8042.nopnp" work for you?

[You-Sheng Yang (vicamo)]

pci 0000:00:1f.5: can't claim BAR 0 [mem 0xfe010000-0xfe010fff]: no compatible bridge window

Please help attach your acpi dump info:

  $ sudo apt install acpica-tools
  $ sudo acpidump -o acpi.dump

And attach that `acpi.dump` file.
