I'm getting a kernel panic (or at least something wrong going from
3.7-rc8 to 3.7). There is no output, it just kills my computer when I
plug in a power supply. I have bisected the kernel from 3.7-rc8 to
3.7, here is the output:

    watchdog: Fix CPU hotplug regression
    Norbert reported:
    "3.7-rc6 booted with nmi_watchdog=0 fails to suspend to RAM or
     offline CPUs. It's reproducable with a KVM guest and physical
    The reason is that commit bcd951cf(watchdog: Use hotplug thread
    infrastructure) missed to take this into account. So the cpu offline
    code gets stuck in the teardown function because it accesses non
    initialized data structures.
    Add a check for watchdog_enabled into that path to cure the issue.

I am not proficient in C or anything, but I will be reporting this
upstream. I'm on a Lenovo T420 with an i5-2520M cpu.
