Thank you for the patch. The panic and the dead lock disappeard, but 
there is a new problem insteed. The commands

mkfs.xfs /dev/ad8s4
mount -t xfs /dev/ad8s4 /home
mkdir /home/lothar
chown lothar:lothar /home/lothar

/var/log/messages showed this debug output for the above commands:

scp somehost:/some-tarfile.tar.bz2 /home/lothar
tar xjvf some-tarfile.tar.bz2
