I also have a lot of scsi tape weirdnesses on 2.1.121. Specifically, stupid mt tricks don't work anymore (mt bsfm gives I/O error sometimes). No panics though using vanilla 2.1.121 on AIC78xxx with Archive Python DAT drive.
Plus if I try to dump some filesystems, the dump process hanges on down_failed forever:
100 0 367 366 0 0 1028 608 wait4 S p2 0:02 dump 140 0 368 367 0 0 1052 660 unix_data_w S p2 0:00 dump 44 0 369 368 0 0 0 0 do_exit Z p2 0:00 dump 44 0 370 368 0 0 0 0 down_failed DW p2 0:00 (dump) 40 0 371 368 0 0 1028 616 down_failed D p2 0:00 dump
Getting back to 2.1.120 in the meantime...
Phil.
