Thanks Thom!

We've also discovered a simple and interesting test to break systems :(

Run this, and at some point, if your clocksources are unstable, your
system will hang, and eventually crash:

  while true; do sudo hwclock ; sleep 1 ; done

We've run this across 2.6.18, 2.6.2[45] and set the clocksource in
menu.lst to each of: tsc, hpet, acpi_pm, jiffies.  We can crash them
all :(
