--- Comment #8 from Ed Santiago <freedesktop-aVMt7ygKTj2t/hvpvFFPbQ@public.gmane.org> ---
Same issue. Dell M4800 with QHD+ display -- NVIDIA Corporation GK106GLM [Quadro
K2100M] (rev a1), 3.16.6-gentoo (I tried 3.17, that didn't even give me a
usable display).

None of the workarounds were effective for me: nouveau.nofbaccel=1 causes
suspend to fail, and so did reverting ecf24de071f4f6cea79ecef5d990794df5875ee1:

   A dependency job for suspend.target failed. See 'journalctl -xn' for
details.
