A couple of basics: 1. What version are you running? I'm guessing 5.3-Stable. 2. Does /boot/loader.conf disable ACPI? How about /boot/device.hints? (hw.acpi.0.disabled="1") It looks like you are starting ACPI which will block apm even if it is in the kernel. Since APM never really starts, no /dev/apmctl is created and ampd can't start without /dev/apmctl. (Note: You will nave /dev/apm with either APM or ACPI.) Do you want/need to run with APM? On older hardware it is often much more stable than ACPI, but on newer hardware it is often getting pretty limited and may be vanishing completely in some cases. ACPI is the way of the future and, for new hardware may be the only way the system will run, but, if your system does OK on APM, it may be a safer way to go for laptops in particular. (I run ACPI on my laptop, but I may just be a bit crazy.) -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
