Hi, same problem here on Radeon HD7850. Unfortunately it seems to be kind of
unpredictable yet,  sometimes I can run a game for hours and it is rock solid,
but sometimes I have to restart the system couple of times and it freezes in a
row. However, I have a feeling, that more demanding graphics bring the GPU to
freeze faster and more often. I also attached myself via ssh from another
machine to be able to analyse it. Currently my system is running xorg-server
1.18.3, but older versions did freeze also. If I activate DRI3 lockups seem to
come more often, but as already mentioned, this is not very reliable
observation. I'll try to do more accurate analysis, please tell me if you have
a hint where to look first please.
