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.
