I have a Tyan S2462 Thunder K7 motherboard. I was hoping to get power-down to work. So I installed FreeBSD current with ACPI enabled. When I typed "shutdown -p now" the computer halted, and then the video card switched off, and the fans kept running. The computer was frozen - even the power-off power-on button wouldn't work. Actually the power-off button doesn't work at all under FreeBSD-current. (It is a soft power-off button that dmesg shows is detected by the OS.) I should add that power-down works great with Windows 2000. Also, the power-off button works properly with FreeBSD-stable. I am thinking that maybe I need to wait a few more months until ACPI is fully debugged. On the other hand, maybe you guys would like to work on this. I can send all info like dmesg, and the kernel configuration (which is basically GENERIC with stuff removed, and SMP and pcm added, but actually it didn't work with the generic kernel either.) Is it possible that power is cut to the CPU's, but not to the fans? Is there anyway to tell? Will I have to "program" the ACPI (that is take the output of acpidump and edit it)? It does seem to me that ACPI is working in some form, just not properly. If I boot up with ACPI disabled, then it works just as in FreeBSD-stable, that is, the power-off button works well. -- Stephen Montgomery-Smith stephen_at_math.missouri.edu http://www.math.missouri.edu/~stephenReceived on Mon Aug 18 2003 - 17:13:11 UTC
