--- Comment #3 from rainer at ultra-secure.de ---
After updating the firmware, I still get panics.

The handbook should be clearer about the fact that you can't get a crashdump
from ZFS.

After adding an additional swap-partition on an USB drive, I got this
crash-dump:

(ewserv-log03-prod </root>) 0 # kgdb /boot/kernel/kernel /var/crash/vmcore.1
