Sounds like an issue, but I don't think you need to recompile a kernel to get APM, if you add 'hint.apm.0.disabled=0' to /boot/loader.conf it should load with GENERIC. It does on 5.x anyway, though I did compile an APM kernel later, after getting things going that way. > There is no update to my machine BIOS as far as I know.

I still think that may be a KPPP issue, but we need to see your dmesg as to whether ACPI is being used/detected (which likely won't work well if at all with a machine that old, whereas APM is much more likely to).

Sad but true. 4.x GENERIC had APM in kernel iirc, 5.x and 6.x don't. > I've been seriously thinking about getting a copy of the legacy FBSD 5.5 > that's on the website. Maybe there isn't a difference between it and the 6.2 > as far as this powerdown issue is concerned. I'm running 5.5-STABLE here on a Compaq Armada 1500c, using APM. I could be wrong, but I don't think the APM code has changed noticeably between 5.5 and 6.x, so I really wouldn't recommend going back to 5.5 until you've tried resolving this on 6.2 first, using the hints in /boot/loader.conf first, and if necessary compiling APM into kernel. Your /var/run/dmesg.boot, please, both re this and the sio issue. Cheers, Ian
