 > 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): 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)
