Just on the off-chance that the keyboard is not completely locked up,
try enabling the DDB option in the kernel config and see if you can
CTL-ALT-ESC into a DDB prompt from the console when it locked up on you.
If you can, do a 'trace' and a 'ps'.
Also check to see if you are running any processes that use special
scheduler queues (aka idprio or rtprio). If so, try not running those
processes and see if the system locks up on you. Note that 'ntpd' will
often run at a realtime priority. Try killing ntpd if you are running it.
