I don't see the attached patch in Linus' tree as of yet. Do you plan on submitting the patch for inclusion in the mainline tree? If so, it would be best to also cc stable, so it lands in all of the stable trees, including upstream 3.13, which Trusty is based on.

However, once I switch to 1080p quality, the flash player crashes, and this happens at the mesa vdpau driver level because a Bus Error triggered by mesa since the CPU can't access properly to gpu VRAM. The same happens loading a 1080p video using VLC or MPlayer (see vlc backtrace http://paste.ubuntu.com/7405255/). Here's the problem as explained by Christian König: > It's not the VDPAU driver that's failing here, it's the kernel. > > When the kernel can't place a buffer into visible VRAM the buffer > should be moved into GART instead for CPU access. But instead we > just return a SIGBUS to the application effectively crashing it. I'm attaching the patch that fixes this problem, provided by Christian and tested successfully on ubuntu Trusty kernel.
