Thanks for the bisect, Ben.
Please test the patch below.
I assume even without the patch, booting with "acpi=off" on your
BIOS-ACPI-disabled box works? (if no, this patch will not solve
all your problems, for you have additional trouble elsewhere)
I am curious why you're running a CONFIG_ACPI=y kernel
for a box with ACPI disabled. (though yes, it is supposed to work)
I'm even more curious what bad things happen when
you enable ACPI in the BIOS -- can you let me know
and we can try to fix them so the machine can run as shipped?
thanks,
