>Description:
System seems to crash at random times, during casual desktop use.

During the last crash the system was very low on Free memory (around
100M according to `top`), while swap was not being used.

I'm not sure if the backtrace [1] contains the desired output (seems
to start at /usr/src/sys/kern/kern_shutdown.c).  When running kgdb in
/var/crash the output points to ULE instead [2].
