Re: linux-3.7.1: disable and reenable NMI watchdog => panic

[Alexander E. Patrakov]

Hi.

As illustrated by the screen photo [1] (sorry for bad quality),
disabling and then reenabling the NMI watchdog panics the kernel
(3.7.1). This is reproducible in qemu-kvm as well, but I could not get
the nice panic message to pop up there (most of the time, the real
machine just locks up, too). This bug is rather important, as
laptop-mode-tools, by default, try to reenable this NMI watchdog when
AC power appears, and this is how I caught the bug the first time.
