Will somebody remind me what the multidisk panics look like ?
I wonder if my problem is similar.
I get a panic with only one disk if I boot singleuser and do
disklabel -r sd0 (If I do it later it seems to work, no immediate panic)
This is on a IIsi with a current kernel for March 23.


# disklabel -r sd0
