Google only shows hits pointing to an ext4 patch that didn't go in 3.7
proper.

My call trace doesn't look copmlete, but shows "fatal exception in interrupt" and:
timerqueue_del
__remove_hrtimer
__run_htrimer
hrtimer_interruypt
smp_apic_timer_interrupt
<???>
paravirt_read_tpe
intel_idle
intel_idle
cpuidle_enter
I had pretty repeated crashes when plugging power back into my running
laptop, but the display just freezes and I can't get a dump.
For the crash here, I did: suspend to RAM, plug power back in, wake up.
Laptop crashed about 3 seconds after wakeup.
I'm on vacation with no hardware to get a proper crash dump or even
serial console, but I have a bad screenshot.
Boy do I wish this could be saved in some kind of NVRAM instead like on
android.

Grumble, I kind of forgot to add the link to my .config, sorry about
that:
http://marc.merlins.org/tmp/.config-3.7.1-amd64-preempt-20121226
While my crash picture is lame (sorry), I'm happy to provide what else I
can before I go home and can provide a proper serial console crash dump.

Sounds like https://bugzilla.kernel.org/show_bug.cgi?id=51661 which is
fixed by 3935e89505a1c3ab3f3b0c7ef0eae54124f48905 ("watchdog: Fix
disable/enable regression"), expect that in 3.7.2...

That looks like a good match, thank you.
Hopefully this quick thread will help google steer folks who do get a
crash to the right page and fix.
Cheers,
