Comment 217 for bug 453579

@era: Unfortunately I won't edit this bug's title nor reopen it due to reasosn mentioned in comment 215 which refers to comment 206. You should report your issue to Launchpad against the linux package. You can do so by running the following command from a Terminal (Applications->Accessories->Terminal) and it will automatically gather and attach debug information to that report:

ubuntu-bug linux

Please try to provide as much information as possible in the bug description:

    1) The majority of kernel bug are hardware specific so be sure to note what hardware/device is being used.
    2) Document any known steps to reproduce the bug.
    3) Also note whether the bug exists in previous kernel versions of Ubuntu or if it's a regression from previous kernel versions.
    4) Finally, it will help if you can test the latest development Ubuntu kernel version as well as the latest upstream mainline kernel[1].
