I think the aic7xxx driver problem is the "classic" signed/unsigned object problem somewhere in the code. I am going to try to find it now that I have "two" controllers.
The AHA-2940 controller, itself, will not work with SCSI devices that do not disconnect, mixed with synchronous devices that do, on the same bus I figured that the new controller was cheaper than a new tape-drive.
Internal to each controller is its own idea of what logical block is what. I think that, since I did not rebuild any file-systems when switching controllers, I encountered a boundary probem, resulting ultimately in an attempt to read or write beyond the end of the physical media. I don't think the resulting exception was handled properly somewhere. The result being that Linux got trashed and subsequent writes went to other SCSI-bus devices.
I now have brand-new Linux and DOS file-systems, made with this controller. Well shall see...
