I've tested this fix on my Dell latitude E6410. The freezes after a sleep definitely got better, but still seeing some random freezes after my pc wakes up.
Before this patch, the freezes were constant but not anymore. Also the error in dmesg i915_hangcheck_elapsed disappeared. I've included my recent dmesg from last gpu hang. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/626967 Title: MASTER: Hang in MI_WAIT_FOR_EVENT on framebuffer switch. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
