Panic on boot (Re: cvs commit: src/sys/dev/acpica acpi.c)

[Munehiro Matsuda]

Hi Nate,

After the following commit (rev 1.179 and 1.180), my system 
panics at random places on bootup.
If reverted to rev 1.178, everything seems just fine.

I'll try to nallow down which part within the commit seems to
cause problem.

Regards, 
 Haro
