Interesting.  I have been seeing similar behavior when trying to
update my 7.1-prerelase box to current, except that it seems to be
random _which_ disk falls off the mirror.  I'm also seeing panics if I
try to stress the (then-degraded) mirror with the current kernel.  The
mirror is rock-solid with the 7.1-pre kernel.

The panic is "initiate_write_inodeblock_ufs2: already started", and
I've got some details of the other messages I've seen logged up here:

I just added a new swap device, so I'll see if I can actually get a dump once
the mirror rebuilds.
