>Description:
ath(4) crashes on kernel boot on i386 and amd64 booting without ACPI. 

ACPI disabled because of yet another bug which disables a whole PCI bus when ACPI enabled. Booting without ACPI and without SMP triggers another possible problem and gives me no usable keyboard, and I am away from a lab facility to try some networked tests.

amd64 shown on the following images:

Will conduct some more tests, adding information as soon as possible.
Sometimes the crash backtrace looks different.
>How-To-Repeat:
Boot NetBSD/i386 or NetBSD/amd64 with ACPI disabled
Watch the fireworks
