Your message contained only > the panic message and the gdb prompt: I used the gdb -k /boot/kernel/kernel.debug /home/jorn/dump/vmcore.0 command, and the output with the previous mail was the output of that command. A small, perhaps irrelevant sidenote, is that the kernel.debug file was only located in the /usr/obj/usr/src/sys/KERNCONF, and not in /boot/kernel as described in the documentation of FreeBSD. > > #0 doadump () at /usr/src/sys/kern/kern_shutdown.c:240 > > (kgdb) > You want at least a backtrace.
