Notable in that thread:

a post about using "-F" with "trace-cmd" too: http://www.linux-kvm.org/page/Tracing

a post which states: "When booting with clocksouce=hpet, the system does not hang."

a post which states: "Using the wrong clock easily causes hangs. The system schedules a wakeup in 3 ms, wrong clock causes it to wakeup in 3 years, you get a hang for (3 years - 3 ms). "
