Not too long ago Daniel M. Eischen's aic7xxx patches from ftp.pcnet.com were incorporated into 2.0.x and 2.1.x. His patches have worked like a charm for the nearly 2 years that I've owned my 2940U controller (I purchased it before there were any Ultra devices on the market.) Recently, though, someone has been trying to fix obscure bugs in the driver that never manifested themselves on my controller and has screwed up Ultra support in the process. I'm guessing that he doesn't have an Ultra controller on which to test his modifications to the driver. One result of that is that Red Hat 5.0 cannot be installed from a CD-ROM connected to a 2940U controller or to a partition residing on a hard disk connected to a 2940U controller. The current aic driver in 2.1.79 [just barely] works with my 2940U, Plextor 8Plex CD-ROM, and Zip drive, but I don't dare hedge my bets and try a SCSI hard disk.
