On either 2.6, or 2.4, booting with ACPI enabled gets as far as
parsing the ACPI EC table - at which point it oops with bad pointer
and halts the system. Sorry at this point I don't have the register
contents; it took a while to narrow it this far - and have the
screen in such a state that I can see any relevant information other
than the the trying to kill init message :)

Could you try, say, 2.5.70? That would help me understand if it's a
regression or not.
If that also fails, then I think determining exactly where it is oopsing
(probably via printks) would be the next best way to go.

This is the 2.5.74 patch for P4 kicking in. Without it
you wouldn't have access to the local APIC.

Since 2.4 also oopses it can't be the local APIC. I'm saying
this because ACPI + local APIC doesn't work with some BIOSen.

looks to be the same problem, I got a little more info - and compared
it to 2.6.0-test2-mm1; forgive the formatting, this was copied by hand
(its a pain being with only one box):
anything before this was cut of by the size of the screen

that'll help with anything (can't make much sense of it myself, but
was surprised to see special casing for win98/nt/me in the init section)
