The error message says one of the device drivers failed to suspend 
properly.  When that happens, acpi(4) refuses to suspend for "better 
safer than sorry" reason.  You can try one thing, though.  Remove all 
non-essential device drivers from kernel configuration and build a 
bare minimum kernel, which is just enough to boot your machine.  If 
this kernel suspends successfully, then try adding one driver at a 
time until you find a culprit.

Good luck.
