Created attachment 890201 [details] Fix intel reset crash. Description of problem: Newer kernels (3.14+) apparently trigger a bug in Mesa that causes crashes when using older Intel GPUs (Ironlake in my case). There is an open bug at https://bugs.freedesktop.org/show_bug.cgi?id=75723 with a patch that fixes the problem. The attached change adds the patch to Fedora's mesa package. It is also available in the intel-reset branch at https://git.ikkoku.de/git/suraia/fedora/mesa Please also merge to Fedora 20 because kernel 3.14 is on its way there, too. Version-Release number of selected component (if applicable): 10.1.1-2.20140419.fc20 How reproducible: Always. Steps to Reproduce: 1. Start Chrome 2. Access chrome://gpu 3. Check whether GPU acceleration is available Actual results: GPU acceleration does not work because the GPU process crashes. Expected results: GPU acceleration works.
Looks like this same bug is hitting a lot of kde/kwin users (with desktop effects enabled), including me. Side effect also screen brightness controls no longer work either, but I'll double-check that once crashes are gone. I'll try testing the upstream fix asap.
I think this is the reference to the upstream commit fixing this, http://cgit.freedesktop.org/mesa/mesa/commit/?h=10.1&id=2a51539bbc0a112d6d37c402465b07002bd59722
Scratch build with that patch on top of mesa/master branch, http://koji.fedoraproject.org/koji/taskinfo?taskID=6813089 fixes crash for me. (though still have brightness problems, will continue to blame kernel for that)
I am a KDE user affected too. This bug disables some capabilities in my system.
Looks like Mesa 10.1.2 is out, which includes the fix.
Created attachment 892875 [details] Update to 10.1.2. I have updated the package to version 10.1.2; feel free to pull from the mesa-10.1.2 branch at https://git.ikkoku.de/git/suraia/fedora/mesa or use the attached patch. Disclaimer: I have also modified the spec file to use the upstream tarball instead of a Git snapshot.
