Subject: linux-3.9: OOPS in intel_timer_pstate_func

Hi,
  I just this kernel crash on my laptop running fine so far on 3.7.10 (and 3.8.5
if really necessary). The 3.9 was running for maybe 2 hrs, at the most. :(

  I just opened a bug at https://bugzilla.kernel.org/show_bug.cgi?id=57401
with a camera picture of the screen with the stacktrace. I failed to find
a component like CPU or IRQ so please forward this to the appropriate person.
Thank you,
Martin
