That's not good. Do you have a persistent message buffer across
reboots? If you have DDB compiled in, the system will print a stack
trace to the console if entry to ddb is not enabled, before rebooting.
If you have a persistent message buffer, you can find this with dmesg.
If not, you could hook up a serial console and and log the output.
