To check this from the GFX side, could you open a bug at [1]? Please try suspend/resume without the graphics driver loaded (booting with nomodeset) and if that works suspend/resume with first setting one of the test phases in /sys/power/state. Trying the drm-tip branch from [2] would be also helpful. Please provide the dmesg logs at each run when GFX is enabled, booting with drm.debug=0xe. Using netconsole or pstore could help gathering the log when the machine just powers off.
