It's good to quickly get to the root cause :) Can we possibly detect
whether we are in a virtual machine and hence skip this particular
test case?

cpu_has(&boot_cpu, X86_FEATURE_HYPERVISOR)

Yeah, but then it is still broken on non-x86 code (the test lives in
core kernel).

As it is just testing the events for wakeup, I could probably just add a
completion and force the other thread to just wait for it. I'll write up
a patch. But it wont make it in till 3.7.

That would be better.  A hypervisor might be real-time capable (with
some effort kvm can do this), so we don't want to turn off real time
features just based on that.
