Hello, I'm having an issue with my AMD Sempron box. It randomly crashes/reboots. I have no been able to catch it in the act, I just find the aftermath the next time I log in. It does not drop any core files in /var/crash and has no strange messages in the log files. I have even built a custom kernel with KDB and KDB_UNATTENDED options, but there seems to be no traces. Any tips/help is appreciated. If more info is needed I will provide what I can.
