While playing arround I got a panic:

GEOM_GATE[0]: Device ggate2 destroyed.
korso:~#65: ggatec create -u 2 10.0.0.1 /dev/ad4p3
korso:~#66: mount /dev/ggate2 /mnt
korso:~#67: dd if=/dev/zero of=/mnt/testfile bs=32k
dev = ggate2, block = 3704, fs = /mnt
panic: ffs_blkfree: freeing free block
Uptime: 1h6m55s
GEOM_RAID3: Device BIGVOL: provider raid3/BIGVOL destroyed.
GEOM_RAID3: Device BIGVOL destroyed.
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort

Unfortunately it's a CF-based server, no space for debug kernel, nor do I 
have a HD as dumpdev. But I guess this is easily reproducable
