Software: Debian unstable x86_32
When booting up 2.6.29-rc2, the system hangs hard somewhat randomly (usually
when loading kernel modules). No reaction to sysrq. I used bisecting to track
down the problem to the following commit

acpi: fix of pmtimer overflow that make Cx states time incorrect
Reverting this on top of 2.6.29-rc2 gets rid of the hangs. I'll attach my
config. 2.6.29 is not affected, so this is a post-2.6.29 regression.
