Any idea how to fix it? There is no keyboard or mouse detected. I think
it works ok on ppc64, Anton did not complain yet.

Hi,

It looks like it is hanging in checking AUX, while writing data into
controller. It is simple outb but it is stuck... Could you please
reboot with i8042.debug boot option and resend the log. Also, you may
try booting with i8042.noaux to check if keyboard alone works.
