[Bug 653547] New: kernel BUG related to ext4/jbd2
https://bugzilla.novell.com/show_bug.cgi?id=653547 https://bugzilla.novell.com/show_bug.cgi?id=653547#c0 Summary: kernel BUG related to ext4/jbd2 Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: x86-64 OS/Version: openSUSE 11.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: syntron@web.de QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=400150) --> (http://bugzilla.novell.com/attachment.cgi?id=400150) two crash reports User-Agent: Mozilla/5.0 (compatible; Konqueror/4.4; Linux) KHTML/4.4.4 (like Gecko) SUSE Since last week (last kernel update?) my server crashs from time to time. After some crashs I installed a forwarding of the syslog and recorded the attached crashs. They seems to be related to the ext4/jbd2 code, but different ext4 partitions are listed in the crash report (sdb2 and sdc2): kernel BUG at /usr/src/packages/BUILD/kernel-desktop-2.6.34.7/linux-2.6.34/fs/jbd2/journal.c:312! kernel BUG at /usr/src/packages/BUILD/kernel-desktop-2.6.34.7/linux-2.6.34/fs/jbd2/checkpoint.c:771! These are the first two crash I could record this way. Normaly the systems halts (no input via keyboard and no network access via ssh). Due to the fact that the crash is related to the disk no information is written to the logs. At the moment I'm back to kernel 2.6.34.7-0.4 as I hope this one will survive. The kernel of the secound bug report is tainted. It uses the nvidia driver as I suspected the noveau driver. If you need more information I can use another kernel; but I would like to be on the save side as this one is my data server. Reproducible: Sometimes Steps to Reproduce: 1. boot system 2. work some time 3. Actual Results: system crash; no access; hard reboot needed Expected Results: working system -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The changes between 2.6.34.7-0.4 and 2.6.34.7-0.5
I can't say for sure which kernel was used before the update. I will now switch back to 2.6.34.7-0.5 and see that happens ... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The previous entry was allocated by DRM so that is an obvious suspect of the corruption. It would be nice if we had more messages like this from the debug kernel to confirm this (it could still be a coincidence and something else could corrupt the entry). Anyway, Egbert, could you have a look into this or point to someone who understands DRM / Nouveau?
