As you are aware we prefer to take SRU patches from stable releases. If the patch is not part of a stable release we like it if the patches have at least been submitted to stable for inclusion and hopefully accepted for a future stable release. I went up to LKML and saw that this patch was part of a bulk patch for networking changes that came from David Miller. There is no indication any of these patches have been submitted to stable. Do you plan to submit this patch to upstream stable? Brad

John, The patch rt2x00: Fix failed SLEEP->AWAKE and AWAKE->SLEEP transitions. From Linus 2.6 tree commit 9655a6ec19ca656af246fb80817aa337892aefbf seems to fix the bug http://launchpad.net/bugs/539794. We see that this patch is not in GKH linux-2.6.32.y.git or GKH stable-queue.git. Any chance that this patch is already submitted to stable or is there any chance of doing that? I will be happy to send this to GKH linux-2.6.32.y.git stable if this patch is not submitted to stable. Cheers --- manjo

Ok, this is the 1st time(and last) I am having to do this, I am withdrawing this SRU request. Please do not process this request any further. Looks like the 2 patches I picked from upstream only fixes the issue partially, I came to this conclusion after I pinged the originator of the bug for more clarification before I submitted them to stable. I am back to square one. Cheers --- manjo On Thu, 1 Jul 2010, Stefan Bader wrote: > On 07/01/2010 05:22 PM, manoj.iyer@canonical.com wrote: >> >> My bad...
