Comment 4 Ben Widawsky 2014-03-25 04:10:47 UTC 
There is some confusion here. The original message says the kernel is 3.13.6. The first screenshot is 3.13.6. The last screenshot shows 3.14.0-rc6. The middle is TBD.

Neither of these are the latest drm-intel-nightly. Can you please retest with the latest drm-intel-nightly?
Comment 5 Ben Widawsky 2014-05-28 18:45:14 UTC 
Making the prio lower since hibernate isn't as important as suspend and other power features.

FWIW, I cannot get my machine to resume at the moment. Can you confirm this is still a bug for you?

Disable i915 module failed:
1. boot the kernel with parameter "i915.modeset=0"
2. lsmod still found i915 was loaded.

drm                   208656  2 i915,drm_kms_helper

3. Failed to remove module with commands below, and unable to find which module used i915 module.

[root@x-bdw01 ~]# rmmod i915
