These aren't "spontaneous" reboots. They're kernel panics. > Apr 3 06:50:44 hope kernel: Trying to mount root from ufs:/dev/ad0s1a > Apr 3 06:50:44 hope kernel: WARNING: / was not properly dismounted This is because the machine rebooted without unmounting the filesystems. It will do a background fsck later. > Apr 3 06:50:44 hope savecore: reboot after panic: page fault > Apr 3 06:50:44 hope savecore: writing core to vmcore.3 This means that the reboot was caused by a page fault. A core file was saved (to /var/crash by default), so you can feed it to the kernel debugger kgdb(1) to see what caused the page fault. See chapter 10 of the developers handbook on how to debug a crash dump. Copy the output that kgdb generates when starting up, and the output of the 'backtrace' (or 'bt') command and post them here, or on the hackers list.
