** Description changed: During QA testing of 11.10 on unreleased Ivybridge systems, we have encountered quite a few GPU hang bugs in mesa that take out the desktop that have been fixed in the stable mesa-7.11 branch after 11.10 released. Given that 7.11.2 is quite large and different than 7.11.0 that is in oneiric, I've backported just the fixes for the issues we have found. - These include: GPU reset loop leading to a hard hang of the system when these apps are run on Ivybridge: qgears2, openarena, unigine heaven, trine, minecraft Hard hang of the system when these apps are run on Sandybridge: trine, oilrush Wrong colors rendered in lightsmark on Ivybridge To verify, install phoronix test suite on an Ivybridge system, and run the qgears2 benchmark TEST CASE: 1. log in to desktop on an Ivybridge system 2. install phoronix-test-suite (sudo apt-get install phoronix-test-suite) 3. run lightsmark or qgears2 test (phoronix-test suite run lightsmark) If it fails, dmesg will be flooded with these errors and the desktop will be unusable - Jan 26 12:44:41 u kernel: [ 4260.408090] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
