/etc/rc: WARNING: /dev/apmctl not found
Since a recent buildworld, i have noticed the following on my laptop. dmesg output: -- Starting usbd. /etc/rc: WARNING: /dev/apmctl not found; kernel is missing apm(4) Starting apmd. -- My kernel: -- # Power management support (see NOTES for more options) device apm # Add suspend/resume support for the i8254. device pmtimer -- ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

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.

This is a recent (~1 year old) laptop, but basically i want the os to support all the power managment functions, be able to see the battery status, supsend/resume, etc. Is apmd not required for this?

Yes, they do. Any reason for this? ACPI and APM are mutually exclusive. If one's running the other will refuse to start. The default kernel tries to load ACPI by default first thing unless either of the 2 following conditions are met: 1) The laptop is on a blacklist of machines known to have a fscked up ACPI subsystem. 2) You tell it explicitly *not* to do so. This is done by adding the `hint.acpi.0.disabled=1' hint. - -- G.

Do these need to be set manally? Any reason for this? What you have leaves ACPI as the power management system on you r computer. This is probably a good thing as ACPI will certainly receive better support as time goes on. ACPI is not a new APM. It covers far more things than just power management, but, since it does deal with power management, it can't co-exist with APM. It's one or the other if your BIOS supports both. Old BIOS may not support ACPI and new BIOS may not support APM. Old BIOS that does support ACPI and APM may not have very good ACPI capability, making APM a better choice. If you run ACPI, an APM emulator is also available that provides a limited APM API for utilities that used APM for things like battery life and such. For that reason, you will probably see /dev/apm if either ACPI or APM is running. You will see an apmd process and /dev/apmctl only when actual APM is used. If you have APMD_ENABLE=YES in /etc/rc.conf, apmd will error when started with ACPI. Simply remove the like from /etc/rc/conf if you run ACPI. When you have a little time, issue the command sysctl hw.acpi for a list of things you can read and/or modify. Also, if you are using a laptop, try acpiconf -i 0. (This will probably do nothing on a desktop.) -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
