Hmm, if it works at all, then it really should work all the way ...

There is one difference between 2.1 and 2.0.5: Due to a oversight, CDROMs were used with synch. transfers under 2.1, while only asynch. transfers had been used for them under a GENERIC 2.0.5 kernel. } I don't have the exact screen output, but it looked very similar and I } definately remember the "ncr0: restart (fatal error)" line.

Well, the hardware should be supported better than anything else, since this is the development base for the PCI and NCR code :) The problem you describe can be caused by roo many terminators, for example, and it is well possible that slower transfers still work, but that FAST transfers suffer ...
