Subject: 3.9.4+ watchdog overflow and migration lockup soon after boot (cpu_stopper_thread
 related?)

While trying to verify that the kobject patch
(see "Please add to stable:  module: don't unlink the module until we've removed all exposure." email)
fixed the problems I was seeing, I hit what I believe is a different problem.  Much harder to reproduce
(maybe 15-20 reboots before I saw this..haven't seen it since).

This was on a kernel with additional non-upstream patches, but it's not obviously related to anything
I've been hacking on.  I'm trying to reproduce now on standard 3.9.4 plus the kobj patch,
but this seems to be quite rare, so not sure how long it will take.

There is plenty of sysrq info below, including held locks, cpu backtraces, etc
in case someone has an interest in looking farther.

Any suggestions for patches to try would be welcome.

(gdb) l *(cpu_stopper_thread+0xbd)

287				done->ret = ret;
