I don't think so. I see this on I/O workloads, but not a total hang.

As far as I've been able to tell, UML is spending so much time in the host
kernel that > 10 seconds can pass between timer ticks (which are
supposed to happen at 100 HZ while UML is running in userspace).
The host is doing heavy I/O at the time, but I don't see that excusing
a 1000-fold slowdown in timer ticks.
BB made a proposal a while ago to use SIGPROF instead of SIGVTALRM
since SIGPROF ticks while in the kernel. I think this is a good idea,
but at this point, I think it would just cover over the real problem.
