Capture kernel crash dump

I'm running a full debug kernel and I followed the handbook instructions.

# echo "dumpdev=/dev/ada0p1" >> /etc/rc.conf
# swapon /dev/ada0p1
# dumpon /dev/ada0p1
# dumpon -lv => kernel dumps on ada0p1

After crash (poudriere bulk), reboot & before mounting /dev/ada0p1,
# savecore /var/crash /dev/ada0p1  =>  savecore: no dumps found

What's the mistake?
