Signs of an incoherent batch. I can only strongly recommend you update your kernel.

You may start with that version but if it is still occurring, I recommend to take latest one
Hi is this GPU Hang continue to happen after your update of the kernel? Any update that we can close or move forward with this bug
Hi, sorry for my silence, was too busy. I had no confirmed GPU hangs since the kernel update. There were a few crashes but those probably were hibernate-to-disk related. I did not have time to investigate properly. Could you recommend some test to stress GFX subsystem (either within chrome or not) so that I can provide conclusive answer to your question? I have just installed fresh 4.9.6 kernel. Thanks
If the hang is not appearing problably the updated kernel help with that, I'm going to close the bug, but please if you encounter the problem again open a new bug thanks for the reply
