acpi on asus m6n

[Joey Mingrone]

Hi,

I'm sending this message after reading the "Using and Debugging FreeBSD ACPI" 
section in the handbook.

My system is an Asus M6800N running BIOS version 0209A.  
The output from uname -a is: 
FreeBSD karlsruhe.mingrone.org 5.2.1-RELEASE-p9 FreeBSD 5.2.1-RELEASE-p9 #3: 
Sat Jul 17 20:27:38 ADT 2004     
root at karlsruhe.mingrone.org:/usr/obj/usr/src/sys/KARLSRUHE_MINGRONE_ORG_2004-07-17  
i386

Description of the buggy behavior:
- no battery status
- suspend to S3 often works (with lots of errors in syslog) but it sometimes 
doesn't (network interfaces won't come back up and on rare occasions the 
system will lock up)
- suspend to S4 works, but resuming doesn't.  Hitting keys doesn't bring the 
system back up and hitting the power button causes a reboot with warning 
messages about the filesystems not being properly dismounted.  
hw.acpi.disable_on_poweroff="0" in /boot/loader.conf doesn't seem to make any 
difference.
- DPMS works to turn the monitor off some of the time, and on occasion the 
monitor will turn off while I'm working (I have it set to turn the monitor 
off after 15 minutes of inactivity)

See http://mingrone.org/m6n for:
ASL (acpidump -t -d):
boot -v output
asl compile errors

This Linux patch (which doesn't patch the ASL cleanly) might be helpful:
http://www.tzi.de/~adieling/asusm6n-acpi/

I think that's everything.  
I'm going to play with the ASL and if I come up with any improvements I'll 
post a diff here.

Also, I hope I didn't scare anyone away who was considering this system.  
5.2.1p#9 runs quite well on it.  ..nice screen, gigabit network adapter and 
802.11b/g works with NDISulator.
