Note that the fault condition persisted no matter which clocksource was
in use: I tried all four (tsc, pm_timer, jiffies, pit) and they all resulted
in "sleep 1" lasting far longer than 1 second.

Feel free to email if I can be of further assistance. In the meantime I'll
try 2.6.16-rt12 over the weekend to see if the situation is any different.
