What OS is this?

I've seen this kind of thing with FreeBSD where the kernel timecounter
source has been chosen badly (i.e. choosing TSC when the TSC isn't
actually invariant enough). Forcing TSC not to be used fixes it. The
configuration I've especially noticed it on is when running in a VM with
a single virtual CPU.
