Besides other possibilities, a bug in the kernel could be the cause.
Please check if any process (one or two) is in uninterruptible sleep.
(using ps axl the state is D)
Furthermore, Magic SysRequest+T (alt-print-t) and the dmesg output could
give some hints.
If there is nothing suspicious you might try some profiling tool, e.g.
OProfile.

There was another bug report about a wrap around load average. I dont know
if both reports are related.
