Rod, this is plain untrue and you ought to know it ... (If you happen to have a secret list of incompatible drives: Well, there's not much I can do. You are among the least cooperative persons I ever met (on the net), when it comes to remote error diagnosis and debug sessions ...) There have been a few problems with tagged commands and buggy drive firmware, and they often could be solved by getting a firmware upgrade from the drive vendor. There are a few remaining incompatibilities with cheap CDROM drives (esp. the Chinon 525 and 535). Rod, you are the one who did wine about this before, since you ARE making money out of my work, by selling systems with the NCR, but were too busy to help diagnose the problem. There is one problem with multiple tagged START STOP UNIT commands being sent to certain IBM drives, and those start unit commands are bogus anyway, and while I could filter them out in the NCR driver, I'm waiting for a patch to the generic SCSI code to remove the situation. I have asked for the -DFAILSAFE for all install kernels just to be able to make the driver work, even though it does not use all performance features in the install process. Those will be available in all custom kernels, though ...
