--- Comment #37 from Manuel Ullmann <ullman.bugs@posteo.de> ---
Are you sure this bug is not related to bug #85320? Also, are you certain it is
fixed in 4.0.0-rc7+ (linux git). In the mentioned report users of RV620/630 and
RS780/880 (3450/2600 and 3200/4200 respectively) report GPU Resets and lockups
when using vdpau hardware decoding.
Do you use also mesa git and might the fix be rather introduced by a mesa git
pull? That would explain, why you could not bisect it in linux git.
I for my part have a Radeon HD 3200 Mobility (RS780M) and could still reproduce
it with linux git. Did you test the fix thoroughly? For example I could start a
video with hardware accelerated video decoding in mpv 40 times without a GPU
Reset, but seeking in the video or disabling and reenabling the video track
could cause it, while normal playback usually did not trigger it.
Stable VLC however caused the GPU Reset on the first try using vaapi decoding
with vdpau wrapper. It would be at least a good sign, if VLC can´t reproduce
this anymore for you and maybe for the others at bug #85320 also.

So basically I´m asking, whether the described methods still cause a GPU Reset
and what libraries you use in git version.
