2.4.7-ac3 panic on boot (acpi?)

[Eric Buddington]

Hey all,

I began to report this bug a couple weeks back, under 2.4.6-ac3, but left on vacation before
capturing and parsing the panic.

So here it is on 2.4.7-ac3. My system is a K6-2. Most kernel stuff is compiled as modules.
Kernel 2.4.3-ac3 does *not* exhibit this problem.

Thanks again to whoever implemented serial console support - I would
have spent a lot more time on this without it.
