Thank you for providing a patch, and making Ubuntu better. Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?
People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly. To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel. ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1414789 Title: Kernel Oops - unable to handle kernel NULL pointer dereference at 0000000000000010; EIP is at fb_release+0x26/0x60 Status in linux package in Ubuntu: Triaged Bug description: My laptop has a kernel problem with the Ubuntu 15.04 live disk. The Kernel reports constantly about a NULL pointer reference. Sometimes the X-server starts without the Unity interface and the UI freezes constantly for a few seconds. It often ends with a complete freeze of the computer. Other times the computer freezes before the desktop was loaded. I think it could be the radeon driver for my ATI Mobility Radeon HD 5650.
