Fatal trap 12: page fault while in kernel mode

[Richard Nyberg]

This panic was nasty, the machine didn't reboot by itself and when I
rebooted it myself savecore couldn't find any coredump. The machine
was compiling java/jdk14 plus some other port i a screen(1) when the
panic occured. I've run fbsd current on the same machine for a long
time without any problems.

I don't know if anything helps since I didn't get a coredump but
here it is:
