kernel config for 2.6.35
After updating from 2.6.34 to 2.6.35, my laptop fails to boot with this

BIOS update didn't help. Booting with acpi=off solves the issue.
Using git-bisect I've found a commit that causes this panic:
https://patchwork.kernel.org/patch/106696/ which was a fix for
https://bugzilla.kernel.org/show_bug.cgi?id=16357
Reverting this commit solves the issue.
