I'm not questioning that you haven't seen that error in F17, but we have had quite a few bug reports with similar error messages for a while now. Apparently there are lots of ways GPUs can get hung, so they might be different from what you're seeing. Just wanted to point out that it might not be a new 3.8 change that caused it. josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
