Problem 2 has been addressed in 2.2.0-pre1 (changes to scsi_error.c):
handling of the sense data received from the adapter is changed so that no
more elaborate error recovery is done by the middle-level driver (when
sense data is received, the adapter and the bus are operating properly).
This does solve most of the problems related to tapes (good and bad) and
bad CDROMs and this is the way the "old" error code operates.
