I have done 1000+ cycles so far with patch v3 (on 4-core Ivybridge and no eagerfpu), and did not hit my issue. I let the testing going on, but wrt the issue after suspend, this fixes it with very high probability (ie I have never done that many cycles without hitting the issue). -- Vincent -- 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/
