Package: src:linux
Version: 3.2.65-1
Severity: important
Dear Maintainer,
I wanted to disable journal for my root ext4 filesystem running in virtual Debian Wheezy amd64 (using Virt Manager, KVM machine), but just after remounting filesystem to 'rw' mode with disabled journal, kernel experienced segmentation fault.
Call trace is attached as screenshot because there was no textual information saved after crash. System did not respond to 'reboot' or 'poweroff' or anything afterwards.
System does boot successfully when force-restarded, and I am not sure if there is any damage for filesystem consistency.
To reproduce crash I did like this:
1. Install virtual Debian Wheezy amd64 using Virt Manager with ext4 as single '/' filesystem with default mount options.
2. After first boot, enter single user mode:
init 1
3. Disable ext4 journal using this sequence:
mount -o remount,ro / #tunte2fs needs readonly filesystem to disable journal...
tune2fs -O ^has_journal /dev/sda1
mount -o remount,rw /
*crash*
Output of a crash is seen in attached screenshot.
To reproduce it again:
1. (re)boot system in normal runlevel
2. Enable journal:
tunte2fs -O has_journal /
3. Reboot (again).
4. Repeat from step 2 in last sequence (init 1 ...) to disable journal again.
