@Pascal Hartig: I looked at changes between -11 and -12 kernels, there
isn't anything that looks like to be the cause of the issue.
Besides updating the kernel, did you make other changes? I noticed that
you are using these extra kernel options at boot:
"i915.i915_enable_rc6=1 i915.semaphores=1 i915.lvds_downclock=1
i915_enable_fbc=1 pcie_aspm=force". If you remove them, do you still get
the resume issue?
Also to confirm the working and failing kernel versions, please run this
command on both the working and failing kernels you boot: "cat
/proc/version_signature /proc/cmdline", and paste the result here.
