HillClimber, thank you for taking the time to report this bug and trying to help make Ubuntu better. However, the upstream kernel is not a software package provided by the official Ubuntu repositories. Because of this and as outlined in https://wiki.ubuntu.com/Kernel/MainlineBuilds the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!
