In the case of the last report, I agree it makes sense.
But from the beginning I started this discussion because "* ERROR *
ring gfx timeout" haunts me everywhere. For example I unable to unlock
computer after night. I connect via SSH and see in kernel log "* ERROR
* ring gfx timeout". Or another case I watching video on YouTube as
usual and some times computer are stuck. I again connect via SSH and
see in log "* ERROR * ring gfx timeout". So i am very tired from this
error and want really helps to fix it. But I suppose logs from dmesg
here is helpless. Then I asked the guys how to got really useful logs.
And Andrey was guide me how to do it with umr tool.
I am tried get logs with umr with well reproduced for me case.
So we are here.

Best Regards,
Mike Gavrilov.
