--- Comment #21 from Michel Dänzer michel@daenzer.net --- If there really is a significant difference in stability between Mesa 10.2.y and 10.3.y, it would be interesting if you could isolate which change between them made the difference.
However, from your description so far, I'm afraid the difference might just be coincidence, because we don't understand yet what triggers the problem, so it happens 'randomly'.
