Another one, not sure if related to the last one.
These are easy to trigger, but not reproducible at all even with pretty
exact syscall trace matches. So I'm not sure what's going on.

I've been seeing some more of these lockups up x86_schedule_events(),
not sure if they are related. The fuzzer triggers them often (both
on core2 and haswell) but they are not reproducible with the same random
seed.
This one is on 3.14 on haswell.
