Hi

with RELENG_7 (4-7 days old) I have come across with 2
panic/reboot.

The first hapened while machine was compiling ports. When I came back
the machine had rebooted and coredumped.

Second time was while was surfing while machine compiled
audacious-plugins. Because X was running I did not see any messages.
Laptop just rebooted and dumped.


I could not find anything from log files.
