I also have this problem. The last kernel log message before every crash is always "hpet increasing", and I also have the "clocksource tsc unstable". In practice, the freeze seems to happen when the computer in under some kind of load. For me, it really hates it when there is a lot of wireless activity. For example running p2p applications tends to lead to a freeze faster than just browsing the net.
