Subjectperf : fuzzer-related NMI lockup
Hello

so my perf_fuzzer has been causing problems again.

After running a while all login shells on the system (even unrelated
local ones) get killed. Nothing is logged when this happens and it
doesn't appear to be OOM related.

In an attempt to find out what was going on I ran the fuzzer with "nohup"
which led to the following NMI lockup which looks perf related. The
system became unusable after this.

The first WARNING is I think a known issue but I'm including it in the
dump in case it is related. It's the NMI lockup that is the problem.

There was possibly some sort of RCU message printed to the screen also
that didn't make it to the logs but I wasn't able to write it down in
time.

This is on a recent ivybridge mac-mini running 3.11-rc3
