Description Michal Ludvig 2007-01-29 17:30:50 UTC

Most recent kernel where this bug did *NOT* occur:
Distribution: OpenSUSE 10.2 x86
Hardware Environment: 
SCSI controller "LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual
Ultra320 SCSI (rev 07)", tape streamer Datastor LTO1 (don't know the exact model)

Software Environment: OpenSUSE 10.2 x86, mondoarchive, mondorescue

Problem Description:
Attempt to restore data from a tape drive results in the following Oops and
subsequent functinality loss of the strreamer. Writing to the tape, however,
worked fine. Or at least mondoarchive haven't complained.

Following kernel Oops happens on both self-compiled vanilla 2.6.20-rc5 and
original Suse kernel 2.6.18.2-34-default, both are compiled with GCC 4.1.2. As
soon as I recompiled 2.6.20-rc5 with the exactly same config on an older Suse
with GCC 3.3.3 it fixed the problem.

Oops log

This is from the kernel compiled with GCC 4.1.2

Comment 2 Michal Ludvig 2007-01-29 17:37:00 UTC

Created attachment 10219 [details]
.config used

Same config was used when compiling with GCC 4.1.2 as well as GCC 3.3.3

I don't know how mondoarchive uses the tape. The bug 7900 looked somewhat 
similar. It might be useful to try the patch provided for that bug (in 
Bugzilla and linux-scsi).

Comment 5 Michal Ludvig 2007-02-03 03:20:15 UTC

Err *this* is bug 7900.

FWIW Later that day I found that even simple "tar tf /dev/st0" triggered the
Oops, so it isn't mondo-related.

Comment 6 Oliver Paulus 2007-02-12 11:37:13 UTC

Hello,

I get a kernel oops if I want to read from my SCSI HP tape (C5683A) drive -
using tar command too. Mondorestore is calling tar - but a simple "tar tf
/dev/st0" is triggering the oops too. 

Here my system information:

I get a kernel oops if I want to access the /dev/st0 with tar (or mondorescue
restore - because this program uses tar too). Here the oops info:

Here my ksymoops info:
ksymoops 2.4.11 on x86_64 2.6.18-3-vserver-amd64.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.18-3-vserver-amd64/ (default)
     -m /boot/System.map-2.6.18-3-vserver-amd64 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod

Comment 7 Oliver Paulus 2007-02-16 15:22:17 UTC

seems to be a copy of http://bugzilla.kernel.org/show_bug.cgi?id=7156. I have
compiled a new 2.6.18-5 kernel with the patch provided in
http://bugzilla.kernel.org/show_bug.cgi?id=7156 (with minimal changes).
Everything is working now.

Comment 8 Oliver Paulus 2007-02-16 15:24:36 UTC

sorry - the posted bug id in the prior post is wrong.

seems to be a copy of bug 7919. I have compiled a new 2.6.18-5 kernel with the
patch provided in bug 7919 (with minimal changes). Everything is working now.

Comment 9 Natalie Protasevich 2007-08-01 07:34:36 UTC

Michal, can you confirm that your problem is fixed in the recent kernel.
Commit 9abe16c670bd3d4ab5519257514f9f291383d104 should take care of the problem.
Thanks.

Comment 10 Michal Ludvig 2007-08-05 05:26:49 UTC

Hi, unfortunately I can't verify it as the HW is now in production and I can't play with it anymore. Sorry for that :-(
