-- Previously Posted to FreeBSD-questions Update: I've changed the RAM in the machine. That seemed to fix the problem for a little bit, but the problem has started occuring again. Also, I'm not subscribed to the list, so please reply to this message directly. Thanks for all your help. -- Hello, Recently, I've been having kernel panics on 4.8RC. This made me upgrade to 4.8-STABLE hoping that the problem would be solved. Unfortunately, I've had no such luck. The panic happens about 1 hour after the machine is booted. Once booted and the panic occurs, the machine will reboot itself for literally hours, until such time as the problem magically goes away. The box has been up for about a day now with no reboots. I'm scared to play around with anything that might cause a reboot as I can't afford this box to have downtime of ~8 - 12hrs (it's a remote machine). If additional information is required, please let me know. The file that the kernel is generated from is a pretty generic copy of GENERIC with IPFIREWALL compiled in. Any help would be appreciated.
