It seems that suspend works properly on your platform, except that the graphics
driver fails to bring the screen back.
It could be caused by the nouveau related kernel parameters you're using, but
anyway, I think we need graphics experts here.
Bug reassigned.

  With 4.7.0-ARCH-13902-gd491e80 and no_console_suspend the LVDS just did not
come up again under init=/bin/bash (i.e. it stayed black while it was still
possible to enter commands blindly) - basically a regression when testing the
bare kernel (tested with a Celsius H270); interestingly when I tested with
nouveau the LVDS came up normally.
  Could it be that these problems are related to the following:

  at least tested to work fine when nouveau is loaded since commit
65ea11ec6a82b1d44aba62b59e9eb20247e57c6e (Ville Syrjälä - x86/hweight: Don't
clobber %rdi); gonna test that accurately tomorrow or so; see also: bug 153371,
bug 153361, freedesktop bug 93887
(https://bugs.freedesktop.org/show_bug.cgi?id=93887).

  I guess it would already be resolved but Bug 155511 inhibits me from testing
that out correctly.
