bah. I've got an Ultra1 in production, and it shows no such problem. I just fired up an Ultra1E, though, and it does confirm your observation. One of the places where the U1 and U1e differ is in the SCSI system. My U1e is not in a great shape at the moment, so please feel free to revert the change you are suspicious of, and see if that solves your problem. And put a PR in with the results, either way. I'll get my U1e back up to shape eventually, but you've got a head start on me. :) Nick.
