So it might in the end of the day the same thing as I have reported in https://bugs.freedesktop.org/show_bug.cgi?id=76554 which is not 100% reproducible either (although with newer kernels it's *much* more reproducible for me than with older). > It worked few times on -rc5, but then I rebooted and problem > re-appeared. If you could capture dmesg of the resume where X fails to resume properly to see whether you have i915 ring initialization errors there as well? -- Jiri Kosina SUSE Labs
