--- Comment #136 from haro41@gmx.de ---
Thank you for testing and reporting back.
I think the crashes are caused by voltage drops, followed by a hardware
failure.
That would explain the many different kernel logs too, because from the drivers
pow, it is randomly.
If vsync is enabled, mclk level is switched at least twice per frame (down/up).
And in some cases i have seen more switches inside a frame.
I am not sure, if this fast memory clock level switching, multiple times during
a frame really useful? It saves not much power, but makes the system instable,
apparently.
I don't think this is wanted behavior, it looks more like a firmware bug, imo.
Maybe an opensource driver developer can help us to understand?
