with the above patch the problem got not really cured here. It just happens more seldom. So there is still something wrong with the blit code in d-r-t.
oh that's too bad, I tried the patch for a couple days now and it did seem to improve things, namely I haven't managed to crash the system anymore (I'm not using it heavily though, is this related to the gpu load or is it somewhat random ?)
