I have a somewhat weird problem with my tape drive, an Archie 2150S.
386DX40 16 MB RAM
Quantum LPS540S on SCSI ID 0
Quantum LPS425S on SCSI ID 1
Archie tape on SCSI ID 4
Whenever I try to access the tape (via tar, cpio or dd), the tape rewinds
for a few seconds, then I get a SCSI timeout error foer targets 0 and 1
(ie the disk drives). When the tape starts running, everything seems to work
OK. After the tape operation is completed, I get lots of messages complaining
about unexpected interrupts.
This did not happen with kernel 1.08, but with all later kernel versions
I was using : 1.1.35, 1.1.59 and 1.1.73. Still worse, 1.1.35 and 1.1.59
got a kernel panic with the message "can't find free mailbox for aha1542"
I assume the SCSI bus is not released while the tape is rewinding, so the disks
cannot be synced.
Additionally, from time to time I get lots of messages "inode xyz already
cleared." which sure as hell make fsck fail on the next reboot.
So, what am I doing wrong ? The tape works fine with my Sun-3/60, so it can't
be the drive.
Any help is appreciated !
Thanks a lot,
