Sorry I assumed the autodetection of bugzilla would set the 
proper type. Changed it now.

Hi,

can you apply the debug patch attached and send me the modprobe output again.
The patch is against stock 2.6.29 but it should apply fine against 2.6.29-rc7.

Thanks,
Boris.

Hi,

yeah, the driver is quite broken but no worries, we'll fix it :).

So, on to the next thing: If my analysis isn't completely wrong, we get a
divide-by-zero error because tape->buffer_size is somehow 0. I'd like to see
what capabilities your drive reports so please apply the following combo patch
ontop of the "tmp fix 2"-patch and please send me the _whole_ dmesg this time.

Thanks,
Boris.

Hmm, seems like the buffer is quite botched or the drive replies with some mode
parameter headers I cannot correlate. Ok, let's now enable full debugging -
please apply the following patch ontop of the other two you have already
applied on your tree. This time you should expect more output so you should add
'log_buf_len=10M ignore_loglevel' to the kernel command line to make sure you
catch it all. And as always, please send me the whole output.

Thanks,
Boris.

If you mean this line:

[   42.272638] caps:  70 0 6 0 0 0 0 a 0 0 0 0 29 0 0 0 0 0 0 0 0 0 0 0


this is the extended sense data with its characteristic 1st byte of 0x70,
8-byte header with sense key UNIT ATTENTION, 10 bytes of additinal length and
ASC of 0x29 meaning "reset hs occured".

Hi Mark,

can you please try 2.6.30 to see whether the problem still persists?

Thanks,
Boris.

Hi Boris,

I didn't test before since I thought the fixes would be in 2.6.31-rc1.
I just tested 2.6.30 and the drive still causes an OOPS.
I'll test again after 2.6.31-rc1 is released and if it still crashes
I'll post a full dmesg and OOPS report.

Regards,
Mark

Hi Mark,

can you send the OOPS with 2.6.30?

Thanks,

I tried to get the OOPS but the system hung and I wasn't able to capture it.

I just tested with 2.6.31-rc3 which didn't OOPS, but files written to the
streamer were truncated when read. I hope to find some more time this
weekend to do some more testing and see whether there's a pattern in the
truncating. Just wanted to let you know to see whether it rings a bell.

I just did some more testing by writing files of different sizes to the
streamer and reading them back. With the 2.6.24-debian kernel the files had the
same size before and after writing. With 2.6.31-rc3 they all return smaller as
written. I did three runs on 2.6.31-rc3 which all produced the same results.

Hi Mark,

ok, we have to wheel out the heavy guns. In ide-next I've got an
ide-tape debugging patch for the whole driver. Get the tree at
git://git.kernel.org/pub/scm/linux/kernel/git/davem/ide-next-2.6.git and
apply the patch at http://bugzilla.kernel.org/attachment.cgi?id=22782
and catch the _whole_ output while doing only one filesize, let's say:

cat /tmp/32 >/dev/ht0
cat /dev/ht0 > /tmp/32.copy


Try setting log_buf_len=10M kernel parameter in case the output gets
truncated since it is quite a lot.

Thanks.

Hi Mark,

I am curious just for completeness of the record about how recent kernels
behave here. (I don't expect they'll be any different since there haven't been
any real fixes since v2.6.32-rc1 as far as I can tell.)  In particular, can you
still use the tape streamer without crashing or lockups, and does it still
truncate files when you try to copy them with dd?

Also, can you bisect[1] to find the particular change that introduced the bug?
(That would make it easier to find a fix, for example by backing that change
out.)

Thanks,
Jonathan

That's good to hear :-)

I also managed retested the drive, this time with
2.6.30-rc5 + ide-phase2 + my ide-phase2 compilation fix patch
+ IDETAPE_DEBUG_LOG

This combination seems to work :-) I wrote a small file to the tape and
could read it again.

After this test I played and tried some more things and got another
kernel warning. I haven't been able to reproduce this consistently but
it seems to occur after playing a bit with:
- writing a file to the drive
- use rewind on the drive
- use fsf 1 on the drive
- reading a file from the drive
(I know fsf 1 on /dev/ht0 is rather useless ;-))
I think this problem is not related with the problems I had before,
attached the entire dmesg, from boot to the kernel message. If you
want I can try to find a way to reproduce it.

Thanks for your effort to get the drive working again.

Actually, I meant only the Tejun tree without my patches. Please retry again if
you have the time or just wait a bit - I finally got an ide tape myself :) :

hdb: Seagate STT8000A, ATAPI TAPE drive

I guess similar to yours and I'll get to do testing here which eases bug
fixing largely.

Thanks, acked.

No problem, I've been quite busy myself as well.

I compiled 2.6.30-rc4 + ide-phase2 +  your 'tmp fix 2' patch +
IDETAPE_DEBUG_LOG set to 1

Your other patches gave merge and compilation problems. ide-phase2 also
has a problem when I set IDETAPE_DEBUG_LOG to 1, but that one was
trivial to fix. (I'll send the patch as reply to this post.)

The dmesg contains some errors about hdc and after a modprobe of
ide-tape the system freezes and I need to use SysRq to reboot the
system. So the attached dmesg contains no info about the modprobe.
So I fear the dmesg is not too useful, what would you like me to test
next?

Regards,
Mark de Wever

Re: [bug#12874] Seagate STT20000A no longer works

[Borislav Petkov]

Hi,

sorry for the delay but I was busy with ide stuff. In the mean time, Tejun has
fixed some ide-tape bugs and has a git tree so if you don't want to wait for the
fixes to trickle upstream and are eager to test :) you could pull from

git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc.git ide-phase2

and give it a run. As always, please send full dmesg.

Thanks.

I tested with 'tmp fix 2' [1] and 'dump drive caps and dbg rqs' [2] and
the patch below applied and had another divide error. Attached the full
dmesg.

:-)

Do you want me to do the full caps debug test [3] ?

Another question; I'm still using 2.6.29-rc7 as test kernel, do you
prefer to keep using that version or move to 2.6.30-rc1?

Haa, thanks for catching that, although the QIC157d document I'm staring
at here states that the drive might return sense data instead of the
requested page, it seems that we don't get any CHECK CONDITION status
otherwise ide_pc_intr would've caught it (stat & ATA_ERR) and retried
the command.

Now, without having tested it since I don't have the hardware, would
something in the lines below be a sensible kludge for now? I guess we
should have similar error handling for the other MODE SENSE call sites
and propagate some error status from idetape_get_mode_sense_results()
upwards to idetape_setup()? Yeah, I know, the driver needs a lot of
massaging in order even to start looking ok... :)
