I had troubles with an AHA-2940 myself, using linux 2.0.21. The computer
would lock up real tight after about 1 minute of heavy disk access. I had
to do a hard reboot to get the machine up and running again. Switching to
2.0.25 & 2.0.26 did not help.

Researching mailing list archives gave me the following clues:

1. AHA-2940 doesn't like Trident video adapters.
2. AHA-2940 wants to be in PCI slot #1.

Basically the card seems pretty sensitive.. tip #2 solved my problem.
Merely pulling the card out and moving it to another slot was what solved
my problem. :-/

Clue #1 seems to be less reliable - I'm using the AHA-2940 in a machine
with a Trident on-board video adapter but it has stopped giving me problems.
The computer is always in text mode though, so that may not mean much.

I'm certainly not going to buy any more 2940's.

Hope this helps..
