--- Comment #6 from David Weinehall <david.weinehall at intel.com> ---
I've tried to reproduce this, but failed; I've tested with eDP, DP, eDP + DP,
HDMI->DVI, and eDP + HDMI->DVI. All of these successfully resume *if* they
manage to suspend (suspend fails if attempted again right after resume).

I'm using BIOS v58 for this though (and another monitor -- if you think that
matters I can try to track down the same model); would it be possible for you
to test with a downgraded BIOS -- either 56 or 58 should work, though 56 has
some performance issues.
