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. Jung-uk Kim
