So without the asus driver loaded, there is no hang?
> "nolapic". In this case there is no hang
and with the asus driver and "nolapic" there is no hang.
But does the video actually switch?
Is the acpi video driver loaded for these tests?
please attach the output from dmesg -s64000 for the failing kernel
as "nolapic" has no effect on interrupts (PIC-mode in both cases),
it is probably an interaction between SMM and use of the lapic
timer that is causing the hang. Do you also see the hang
when you boot with "acpi=off" and press Fn-F8? If yes,
one has to wonder why the LAPIC timer is enabled on this box.
