Comment(by dsd):

 CONFIG_HARDLOCKUP_DETECTOR doesnt catch anything - the system is really
 and truly hung.

 We've caught the crash with __schedule() debug a couple of times now, and
 can confidently say that X is the last process scheduled before the system
 hangs. I believe I've reproduced the issue (or similar) through simple
 graphics driver modifications, which I've filed in #12027 (just in case
 its a different issue).
