Perfect.  With jhb@ _and_ attilio@ patches MPT rebuilt array
w/out problem (tryed adding and removing second disk 3 times
during build, no more crashes  :-)

Going to cvsup to last 7.2-STABLE, be patient (rebuilding).
At a later time I'll report results even on last -CURRENT.
Thanks for your time.


PS: I successfully configured and used serial console for
debug now, next time no more photos  ;)
