The most common issue I've seen is that the default apm line in both the GENERIC and LINT files compiles apm0 support in, and then DISABLES it: # Power management support (see LINT for more options) device apm0 at nexus? disable flags 0x20 # Advanced Power Management ^^^^^^^ So not only do you have to make sure you've added device apm0, you also have to delete/comment the "disable" part: device apm0 at nexus? Once I did this and rebuilt my kernel, I've had no problems powering down on several AMD Athlon/Pentium III/Pentium 4 systems.
