Hi,
I upgraded from kernel 2.2.17 to 2.4.4. I used "make oldconfig" to be sure I
had as many of the prior settings as possible. Didn't change any of the old
settings. I am running under RedHat 6.2. And, yes, I did all the updates
required
to go to the 2.4.4 kernel.
I use a Seagate ATAPI tape drive, model STT20000A.
I have no problems in 2.2.17 doing IDE tape backups using dump, restore, and mt.
In kernel 2.4.4, I get the following repeatable scenarios (which all work in
2.2.17):
* In a full tape dump of about 50MB or so, everything goes smoothly. No errors.
* In a full tape dump of a little over 1GB (to a 10GB tape), I get the following
errors
immediately after the backup completes and I try to write a file mark with "mt":
May 9 16:50:49 isaiah kernel: ide-tape: Reached idetape_chrdev_open
May 9 16:52:05 isaiah kernel: hdd: irq timeout: status=0xd0 { Busy }
May 9 16:52:05 isaiah kernel: hdd: ATAPI reset complete
May 9 16:52:05 isaiah kernel: ide-tape: Couldn't write a filemark
May 9 16:52:06 isaiah kernel: ide-tape: Reached idetape_chrdev_open
May 9 16:54:06 isaiah kernel: ide-tape: ht0: DSC timeout
May 9 16:54:06 isaiah kernel: hdd: ATAPI reset complete
May 9 16:54:06 isaiah kernel: ide-tape: ht0: I/O error, pc = 10, key = 2, asc
= 4,
ascq = 1
May 9 16:54:06 isaiah kernel: ide-tape: ht0: I/O error, pc = 34, key = 2, asc
= 4,
ascq = 1
* In a full tape dump of between 6GB and 7GB, the backup completes, I
successfully write a tape file mark with "mt", rewind, then attempt to compare.
I get:
May 9 04:21:18 isaiah kernel: ide-tape: Reached idetape_chrdev_open
May 9 04:22:35 isaiah kernel: ide-tape: bh == NULL in
idetape_copy_stage_to_user
May 9 04:22:35 isaiah kernel: ide-tape: bh == NULL in
idetape_copy_stage_to_user
May 9 04:22:36 isaiah kernel: ide-tape: Reached idetape_chrdev_open
I also tried SCSI emulation mode (something I didn't have to do in 2.2.17)
and it didn't work either. In SCSI emulation mode, my CD-ROM drive worked
OK in SCSI emulation, but the tape drive still did not work. When I tried:
mt -f /dev/st0 rewind
I got the following errors:
May 10 07:49:33 isaiah kernel: st0: Error with sense data: [valid=0] Info
fld=0x0,
Current st09:00: sense key Illegal Request
May 10 07:49:33 isaiah kernel: Additional sense indicates Invalid command
operation code
I've reverted back to 2.2.17 kernel just so I can do successful IDE tape
backups until I can get this problem with 2.4.4 resolved.
Any helpful input appreciated. Please reply directly, as I'm not a member
of this list. If I'm not stating the problem clearly, or if I haven't provided
enough data, please let me know.
Thanks,
Mark Bratcher
