--- Comment #3 from Alex (linuxale at libero.it) ---
I had a similar problem on a Dell Latitude E5470.
I had the follow error in the logs once reboot the system after a suspend:

Jun 21 07:50:57 sabayon kernel: [drm:atom_op_jump [amdgpu]] *ERROR* atombios
stuck in loop for more than 5secs aborting
Jun 21 07:50:57 sabayon kernel: [drm:amdgpu_atom_execute_table_locked [amdgpu]]
*ERROR* atombios stuck executing 73EA (len 272, WS 0, PS 4) @ 0x7433
Jun 21 07:50:57 sabayon kernel: [drm:amdgpu_atom_execute_table_locked [amdgpu]]
*ERROR* atombios stuck executing 6036 (len 70, WS 0, PS 8) @ 0x605C
Jun 21 07:50:57 sabayon kernel: [drm:amdgpu_device_resume [amdgpu]] *ERROR*
amdgpu asic init failed


And the X never came back to life.

The trick as suggested above was to disable the amdgpu Power Management

GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.runpm=0"

Now suspend and hibernate works like a charm!.
