Marian639, thank you for reporting this bug and helping make Ubuntu better. Please answer these questions:
* Is this reproducible? cdimage. ubuntu. com/daily/ current/ . If the issue remains, please run the following command in the development release from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
* If so, what specific steps should we take to recreate this bug?
* Could you please confirm this issue exists with the latest development release of Ubuntu? ISO CD images are available from http://
apport-collect -p linux <replace- with-bug- number>
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/KernelMainl ineBuilds . 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.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Please let us know your results. Thanks in advance.
