I've already compiled 2.6.31.4 @1000HZ, but I'll compile again and try
2.6.31.4 tickless in the morning. i'll report back with the result - it
usually takes a few days after booting before the Oops occurs, so if it
goes well that might not be until the weekend or early next week.

any idea what actually triggers it?  pppoe? malformed packets from the
internet?  udp/514 packets for rsyslogd?

thanks,

craig
