I dont see a pattern, one time it happened after plugging in the USB headphone, another time it happened while the machine was more or less idle. machine does not reboot automatically ( /proc/sys/kernel/panic is set to 20) most of the time the panic does not make it into the syslog but I have been lucky three times. how to track this down?
