I too have seen a single-ended Exabyte Mammoth tape drive go to unexpected bus free right after receiving the second byte of the PPR extended message (01 06 - bus free). Evidently it does not expect to receive an extended message of that length. I submitted a patch to sym53c8xx_2 in lk 2.4.x a few days ago to avoid PPR on a SE or HVD bus, which fixes the problem for me. Anthony J. Battersby Cybernetics
