Hi all, I have a 4-STABLE kernel that panics at boot. How do I force the kernel to core dump? I know that the handbook says to build a debug kernel and to set the dump device via (dumpon + /etc/rc.conf) but in this case the kernel panics during booting. The handbook says that, if the kernel panics at boot, one can specify the dump device in the kernel configuration file, with the "config kernel" line. I tried something like config kernel dump on /dev/wd0s3b (and variations thereof) but I get a syntax error from /usr/sbin/config. I thought maybe it is possible to specify the dump device at the loader prompt? Am I correct that once you specify the boot device the kernel will automatically dump at panics?
