They are different types of baytrail: n3540, j1900, z3775. With this revert applied, all three machines have the same stress test for over 7 days without failure. I disagree with an action plan that includes the word "wait". Tested-by: Len Brown <len.brown@xxxxxxxxx> Indeed, my question is if we can turn off GFX p-states entirely on this hardware. Is there a command line parameter I can use to do that? If we have one, it will certainly make troubleshooting orders of magnitude easier. Note that the bisected patch commit 8fb55197e64d5988ec57b54e973daeea72c3f2ff Author: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Date: Tue Apr 7 16:20:28 2015 +0100 drm/i915: Agressive downclocking on Baytrail was applied to Linux 3.17-rc1. Thus, this revert should be applied to every stable release back to 3.17. thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
