Hi Oliver,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please 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 589624

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.

Hi Oliver,

When was the last time you tried to boot?

Have you tried upgrading to the latest kernel (Ubuntu-2.6.35-6.9)?

I have been booting successfully on the XM for a few days now.

Would you be kind enough to try again and report back here please?

Currently it seems that the only bug that's blocking xM is bug 613855. With that fixed xM will probably work fine.

If you want to test I generated a kernel at http://people.canonical.com/~rsalveti/maverick/kernel/linux-image-2.6.35-19-omap_2.6.35-19.25rsalveti1_armel.deb with the proposed fix for bug 613855. With this kernel it seems that everything works fine, besides a kernel trace that shouldn't affect much:

Note: as my xM (P8) has memory issues, I need to boot it with mem=256M.

Working fine with current pre-installed 20100830 image (besides the serial trace).
