I'm confused about that one:
[ 8.966364] Disabling NO_HZ and high resolution timers due to timer broadcasting (C3 stops local apic)
This message is nowhere in rc5-mm1. It was in rc4-mmX, but got removed
in the updates.
I forget to mention I reverted the following patches from -mm:
i386-apic-timer-use-clockevents-broadcast.patch
acpi-verify-lapic-timer.patch
acpi-verify-lapic-timer-exports.patch
acpi-verify-lapic-timer-fix.patch
since it did not boot with them.

That's the rework I did yesterday.
I'll undo the reverts I did and try it on top of -mm
Thanks,
Benoit
