Bug Description

Since kernel 3.2.0-91 update in Ubuntu server 12.04 LTS, 5 of our servers have encountered a serious problem and needed to be rebooted after making random I/O operations (LVM, resize2fs, etc...).

All servers that were impacted reported this error in dmesg : kernel BUG at /build/linux-_q8eS2/linux-3.2.0/fs/jbd2/journal.c:832!

This seems to be related to this discussion : http://permalink.gmane.org/gmane.linux.kernel.stable/151231

There is a new kernel version (3.2.0-92.131) available in -proposed that we believe fixes this problem. Could you please test this kernel and update this bug with the results?

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Kernel has been installed without problem on 3 servers.

I/O stress test is in progress... I will update this bug in a couple of hours with results.

Thanks for your help !

No more instability after 5 hours of I/O stress on the 3 updated servers (lvcreate, lvremove, mkfs, resize2fs, etc...).

I can confirm that the bug is fixed with this kernel release.
