To be sure that it dumps where there is enough space I added in my rc.conf :

dumpdev="/dev/ad0s1b"
dumpdir="/usr/crash"

I also enabled VESA in the kernel config file :

device		dpms
options		VESA
options		X86BIOS
options		SC_HISTORY_SIZE=1024
options		SC_PIXEL_MODE

But even if it panics, I have no dump/reboot. And nothing works
(pressing power button) so I'm only able to hard shutdown sadly.
