I also experience periodic freezes. One pattern I am able to see is that
whenever there is a freeze and I cannot log to the box for a period,
/var/log/messages says:

Feb 14 00:06:35 192 kernel: dc0: watchdog timeout
Feb 14 03:14:59 192 kernel: dc0: watchdog timeout

Freezes are always connected with watchdog timeout. Any hints how to dig
further?
