Yes indeed it gets complicated with merges. Personally if I compile virgin/testing/drm-intel as of today, I get a GPU hang on kodi boot (attached dmesg-4.0.0 and crashlog-4.0.0) with a segmentation fault. Else, if I revert before the patchset including: 8fb55197e64d5988ec57b54e973daeea72c3f2ff drm/i915: Agressive downclocking on Baytrail It does work, although with the patchset too but it ends up hanging with >=1080p videos. That's weird as this commit doesn't seem to be linked to the original problem, so it's like if this was simply exacerbating another underlying, older issue that might've been missed. For now I'm running 4.1 from Linus github and it works fine...for now.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
