Re: 2.6.0-test9-mm4 - kernel BUG at arch/i386/mm/fault.c:357!

[Ronny V. Vindenes]

Running the game Enemy Territory triggers this (log is from running it 3
times in a row) every time. Haven't been able to trigger it with any
other programs. Machine is athlon64 running all 32bit.

On a happier note, interactivity problems are gone with the new acpi pm
timer patch.
