Well, your best bet is to disable every driver and make them modules. Boot with the bare minimum necessary for input/output and in single user mode. Try suspend and resume in single user mode. If that works, the problem, most likely lies in the drivers. Try enabling one driver at a time, and retest suspend/resume. This way you can find the problematic driver, if any. Also, try changing the hw.acpi sysctls, namely reset_video. HTH, -- Rui Paulo
