> Cannot install 7.1-RELEASE if the RAID-1 is degraded.
I can install and use 7.0-RELEASE and -STABLE, ditto for
7.1-RELEASE and -STABLE and even 7.2-PRERELEASE if (and
only if) I don't remove any drive when the raid is online
or don't add any drive where the raid is degraded.
Machine is an IBM x335 (installed with 4.2 some times ago
and updated in place every 2-3 month up to 7.1, when I
obtained my first panic on mpt0). My first idea was my
fault on config so I changed SCHED_4BSD to SCHED_ULE (that
is the default on 7.1) because booting from 7.1-live-fs was
fine but still hangs removing or inserting second disk.

The two lines above:
(mpt0:1:0:0): Secondary Online
(mpt0:1:0:0): Primary Online
looks strange (to me) because first disk is in place but second is on
the desk.
I have a spare server now, 7.2-PRE (built on Thu Apr 9 11:56:45).
Any test available (even destructive). Feel free to ask.
(in the meantime I'm going to rebuild with any available debug knob)
