Hm! You sure about that ? I have tried running glxgears for a couple minutes
and have gotten no hang so far.. although when I launch it I get a warning
about IRQs not working correctly and I can see that both X and glxgears itself
start sucking all of the cpu (~50% glxgears, ~50% X). Is that to be expected?
BTW, I'm getting ~1500-2000 fps.
If I recall correctly, I had a problem with opengl apps (say, mplayer -vo gl)
hanging up the system some time ago, but only when KMS was /not/ enabled.
