I managed to git bisect to this commit: clockevents: Prevent clockevent_devices list corruption on cpu hotplug bb6eddf7676e1c1f3e637aa93c5224488d99036f http://patchwork.kernel.org/patch/71157/ I've tested with 2.6.33-rc5 with and without this patch to confirm everything works when I revert the patch. I managed to copy down some of the output, but if need be I can try hooking up the serial port.
