View Full Version : [all variants] Kernel panic, shoddy driver.

Greetings,

One of my test servers has a serial card in it, which handles an external temperature array. Since the card has been operating, I have experienced a few 'random' kernel panics; /var/log/messages would seem to indicate that the card drivers are at fault:


Apr 9 15:05:03 nagios kernel: parity=0 overrun=0No of Errors In ttyD0 brake=0

ttyD is the serial adapter. Those messages come up all the time, but I don't get any output when the system does eventually go down.

I suspect I know the answer, but are there any avenues to explore, given that there are no other drivers available?
