The warning isn't that interesting as we killed the GPU and it didn't recover, which is sad but the only thing we can do it fix the software not to trigger the hang.
I am also having this problem and it seems to be associated with resuming my laptop from a suspend. Reproducible 100% in this scenario.
I can reproduce this also, just mplayer some video and wait until screensaver starts to dim the screen. Also happened with other screen candy activity while doing some audio production. Workaround: use DE with no effects enabled.
This bug report needs some specific steps to reproduce the problem with if we're going to make progress by anything other than luck.
(dropping priority until we have sufficient information)
Closing until such time as the submitter (as opposed to everyone else with a GPU hang) can provide specifics on how to reproduce their problem.
