If you don't get a beep at all, something is hanging before FreeBSD even gets control. Try removing extra hardware, compiling out various device drivers, etc. STR is very hard to get right given the wide number of BIOS-specific bugs that we can't even see from the OS. Add to that the immature state of many X/display drivers in supporting resume and you can understand why even Linux, which has 10x the developers and assistance from Intel employees still has a lot of the same problems. -- Nate
