Bug Description
1. Release:
Description: Ubuntu karmic (development branch)
Release: 9.10
2. Package version:
linux:
Installed: (none)
Candidate: 2.6.31.11.22
Version table:
2.6.31.11.22 0
500 http://
3. Expected behavior
System resumes and ext4 root filesystem is mounted rw as it was before suspend. No journal errors occur.
4. What happens instead
After suspend/resume, the ext4 root filesystem is mounted as read-only. Some journal-errors can be found in dmesg and a manual fsck finds some inconsistencies that are fixable without problems. Filesystem cannot be remounted rw, because it is "write-protected". I don't know how to disable this write-protection, so the only way of continuing is a reboot. dmesg output could not be saved. This happened several times already (unsure, if EVERY time or only MOST of the times).
Additional info:
uname -a
Linux jochen-m 2.6.31-11-generic #36-Ubuntu SMP Fri Sep 25 06:37:51 UTC 2009 i686 GNU/Linux
cat /proc/version_
Ubuntu 2.6.31-
dmesg after reboot and lspci attached.
The root filesystem is on a USB-attached SD-memory-card, because I am testing Ubuntu 9.10 without touching the production system on the harddisk and I don't have space left to have the test system on an own partition on the harddisk.
ProblemType: KernelOops
Annotation: This occured during a previous suspend and prevented it from resuming properly.

if this happens again, I'll try to save the dmesg output to another memory card in order to attach it to this bug.
