Don't know....All my systems report "rev 0" . Most are 2.2.5 Stable or 2.2.6.
What level are you running ???? The card has a white label on the main chip
with a revision level marked on it. The ones we have (that have the problem)
are labeled:
AHA-2940UW
945300-01 E
Our vendor asked Adaptec about the problems, but all they would say is that
they made a number of changes at that revision level. What seems funny to me,
is that out of several hundred 2940's that I have, only a few are Revision E
(and they came in around December) and all the cards that are recently coming
out of the distribution channels are Revision D's.
