I have the same problem. Do you use ntpd? Which version? I suspect
some link between the problem and ntpd.
But ntpd is still a userland program, shouldn't the kernel exert the
ultimate control over who gets to screw with the system's clock source?
In any case, I did a quick grep of ntpd sources and found references to
RDTSC only in the Windows port, so the link doesn't seem obvious.

Right, there is no obvious link (but which hard to reproduce bug is obvious?) but see "http://lists.xen.org/archives/html/xen-devel/2011-10/msg01269.html";. There seems to be some connection.
