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. :(

? cpumask_weight
call_timer_fn.clone
? init_timer_key
run_timer_softirq
? cpumask_weight
__do_softirq
smp_apic_timer_interrupt
apic_timer_interrupt
? cpuidle_wrap_enter
? cpuidle_wrap_enter
cpuidle_enter_tk
cpuidle_enter_state
cpuidle_call
cpu_idel
rest_init
? csum_partial_copy_generic
start_kernel
? repair_env_string
x86_64_start_reservations
x86_64_start_kernel

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
