>Description:
Attempted creating multiple ggate devices with same unit number results in kernel panic.
	
>How-To-Repeat:
	
# dd if=/dev/zero of=/tmp/thingie bs=1m count=10
# ggatel create -u0 /tmp/thingie
# ggatel create -u0 /tmp/thingie
(repeat above command multiple times, after a while, kernel panics in
current process="swi5: clock sio")
>Fix:
Don't do that.
