Are you suspending your host while a VM is running? There is most
probably a long-pending bug in the KVM TSC check logic that declares
that clocksource unstable after resume. I'm seeing this here for ages
and complained about it from the beginning (but I never debugged it :-/).
Of course, this doesn't explain your corrupted spin lock. That might be
a different issue.
