[Bug 626967] Re: MASTER: Hang in MI_WAIT_FOR_EVENT on framebuffer switch.

 

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.
