Serious Trouble with AHA-2940 and new Driver

[Nick Taylor]

Hi

Looks to me like the adaptel driver has moved on quite a bit since your
Debian dist. From my experience there were bugs before but  5.1.17 seems to
work for me (apart from on 3940s yawn).

Look at Doug's site at http://www.redhat.com/~dledford/aic7xxx.html for the
patches

All the best

Nick
