After upgrading to the recent snap, I have been having problems with my Archive Python 4mm Dat drive on a buslogics 946c and the nrst device. Using tar i can do the following: tar cf /dev/nrst0 /dir1 tar cf /dev/nrst0 /dir2 tar cf /dev/nrst0 /dir3 mt -f /dev/rst0 rewind tar tvf /dev/nrst0 <lists files from /dir1> tar tvf /dev/nrst0 <does nothing> tar tvf /dev/nrst0 <lists files from /dir2> tar tvf /dev/nrst0 <does nothing> tar tvf /dev/nrst0 <lists files from /dir3> Using dump, i get the following: # dump 9uBf 2000000 /dev/nrst0 /dev/rsd0a DUMP: Date of this level 9 dump: Wed Apr 17 19:41:25 1996 DUMP: Date of last level 0 dump: Sat Apr 13 08:09:32 1996 DUMP: Dumping /dev/rsd0a (/) to /dev/nrst0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 15855 tape blocks on 0.01 tape(s). DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: DUMP: 15882 tape blocks on 1 volumes(s) DUMP: finished in 92 seconds, throughput 172 KBytes/sec DUMP: level 9 dump on Wed Apr 17 19:41:25 1996 DUMP: Closing /dev/nrst0 st0: not ready DUMP: DUMP IS DONE If I do multiple dumps on one tape it rewinds to the beginning and erases the previous dump (not a very effective backup system ;). This all worked perfectly fine with 2.1.0-RELEASE. I've been poking thru the kernel sources (doing diff's between the 2 kernel sources) and haven't found anything yet. Is this a known problem? Would the people working on this area contact me, I'd like to help as much as I can to help solve the problem. Thanks Andrew
