Comment 8 for bug 1415859

Lenz Grimmer, thank you for taking the time to report this bug and trying to help make Ubuntu better. However, the mainline kernel is not a software package provided by the official Ubuntu repositories. For more on this, please see https://wiki.ubuntu.com/Kernel/MainlineBuilds#Does_the_kernel_team_support_the_mainline_kernel_builds.3F . Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!
