2.6.31-21 boot problem

[Marsupilani]

Binary package hint: linux-image-2.6.31-21-server

After upgrading from kernel 2.6.31-20-server to 2.6.31-21-server I can't boot the new kernel. The System goes to maintenance mode because it can't remount kernel RW, since 2.6.31-14 I hadn't any Problems. When booting the 2.6.31-20-server kernel I didn't have any problems. Because of readonly root filesystem I didn't have any logs from start with 2.6.31-21. All data following are from the boot with 2.6.31-20 kernel:

Hi Marsupilani,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 560545

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

The cause of the problems was a change of data mode of the ext3 root file system:
a while ago I had changed it in /etc/fstab to:
data=ordered
with this kernel i must changed it to
data=writeback
and now with lucid, it must changed back to
data=ordered
or leave the value empty for a succesfull boot.
(now you can see it in a message some lines before to boot stops.
