We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://
If it remains an issue, could you run the following command in a supported release from a Terminal (Applications-
apport-collect -p linux <replace-
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:/
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-
If the mainline kernel does not fix this bug, please add the tag: 'kernel-
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-
Please let us know your results. Thanks in advance.
