>Description:
The server is a setting of read only. 
However, it seems to be able to write it from the client. 
It actually fails in writing, and the kernel panic is caused. 
>How-To-Repeat:
* Server(IP address: a.b.c.d)

$ cat /etc/gg.exports
x.y.z.w/32 RO /dev/ad0s1e
$ sudo ggated

* client(IP address: x.y.z.w)

# ggatec create -o ro a.b.c.d /dev/ad0s1e
ggate0
# mount /dev/ggate0 /mnt
# cd /mnt/
# cp -p /etc/motd .
# head -1 motd
