This is strange that you don't get any dump with that gpu hang. Can you attach kernel log (with drm.debug=0xe) linked to that issue ? If you reproduce, please attached as well gpu dump
Comment 2 yann 2016-09-01 11:33:37 UTC
Closing this GPU hang since there is not enough data to proceed (missing gpu crash dump and/or kernel log). Please reopen if it still occurs and attach then logs.

I didn't get a e-mail when you commented, sorry, only got one after the issue got closed.

It's been quite a while since I had this bug, I didn't play arround since then and the kernel´probably got updated quite a bit, If I get to it I will get the newest and try to reproduce this issue, if it persists ill re-open it.

And I don't know why I get no dump either.
