Hi marwooj,

If you could also please 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.

Works the same (wrong) with 2.6.34-020634-generic.
It is my only Internet connection so when I am with not working nozomi I can not upload this automatic files that uploaded last time.
Is there a way I can do this after booting in working kernel?

[marwooj (marwooj)]

The same after initrd.img-2.6.35-020635rc5-generic
