I have been reading about people's upgrade experiences with the 90x and thought
that I would add mine.  We have a rather old 90x (still has some wire wrap)
with xbif, not cache, and an "old style" cabinet.  The most difficult part
of any upgrade, from 2.5 -> 3.1 -> 4.0 was that fact that 2 of the tapes in 
the 4.0 upgrade had there labels switched.  It took me a little while to 
figure out what the problem was when a read that was supposed to take 30+
minutes took 5, and the 5 minute read took forever.  Other than that, it went
smoothly.  I should say though that this was not necessarily the case with 
other machines on campus; they had problems with revision levels on several
of their boards.  

Also, we are having a problem in which our middle bank of ports hangs, 
seemingly at random.  We have replaced the itp, with no effect.  I am wondering
if something in the 4.0 release is screwing things up.
