the bug report for this issue is here:
http://bugzilla.kernel.org/show_bug.cgi?id=13940

is it possible to bisect which commit between 2.6.30 and 2.6.31-rc5
caused this regression?

Please attach the dmesg from the working 2.6.30
and the acpi=off 2.6.31 to the bug report so i can compare
them to the failing 2.6.31

thanks,
