Guys,
If you really need to get this card working right away, or would just like
to help find the bugs, you could try the following new patch just
released:
ftp.dialnet.net/pub/linux/aic7xxx/aic7xxx-abort-Sep04.patch.gz
There are also other files, including a README, that you should check out.
I've cc'd Doug, as I'm sure he'd like to hear your success or failure
stories..
Incidentally, I know that the adaptec has very touchy termination and
resistence requirements, and requires very good scsi cables for proper
operation.
