The patch makes the panic disappear. But there seems to be a deadlock 
instead. Every access on the partition does block. I did

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

dmesg says:

SGI XFS with large block numbers, tracing, no debug enabled

I'll recompile the kernel with INVARIANTS and WITNESS enabled in order 
to get more information about the problem.
