Re: mpt(4) mirror problems

I've tried a few different csup's now on my X4100 to get back to a 
functioning RAID-1 setup:

- As mentioned below, a full CURRENT csup on 2006.04.04 produced the 
same behavior you saw.  An install from 
7.0-CURRENT-SNAP013-amd64-disc1.iso (2006.03.10 snapshot) boots fine.  
So those were the two bookends that I worked from.

- A backdated CURRENT csup for date=2006.03.30.15.00.00 (previous to 
the last big mpt change) built fine, but produced equally broken 
behavior on reboot.  By the time I got to look at the console, it was 
scrolling a single mpt error line off the screen, which I presume by 
this point in the mpt development cycle is irrelevant.  The system 
never came back up fully, and forced a backout.

- A backdated CURRENT csup for date=2006.03.23.00.00.00 (previous to 
the last two big mpt changes) built and booted fine.

So it looks like the big change on 2006.03.25 is where things went 
awry.  Not surprisingly, the notes for 1.22 say, "Regression testing 
with Fusion RAID instances has not been possible."  I'm CC'ing Matthew 
directly so he's aware.
