Just installed CURRENT snapshot from:
ftp://ftp.se.freebsd.org/pub/FreeBSD/snapshots/200706

I cannot boot it with acpi turned off. It fails when trying to mount root.

When I boot with acpi I get lots of error messages about no hardware response 
(in ec, thermal and battery).

FreeBSD 6.2 can boot when acpi off. acpi on there is errors also. I dont know 
if this is caused by changes in acpi stuff or in other parts of kernel. So i 
dont know if this post should be sent to freebsd-current and not here.


And even thou acpi warns about thermal being non responsive sysctl shows 
correctly my system temperature:  

#sysctl -a|grep thermal

hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.user_override: 0
hw.acpi.thermal.tz0.temperature: 40.0C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.passive_cooling: 1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 85.0C
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 98.0C
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
hw.acpi.thermal.tz1.temperature: 42.0C
hw.acpi.thermal.tz1.active: -1
hw.acpi.thermal.tz1.passive_cooling: 0
hw.acpi.thermal.tz1.thermal_flags: 0
hw.acpi.thermal.tz1._PSV: -1
hw.acpi.thermal.tz1._HOT: -1
hw.acpi.thermal.tz1._CRT: 83.0C
hw.acpi.thermal.tz1._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1




Does anyone know if my system will fail to cool under load?





More on errors and my system information can be seen from dmesg below. It is 
with unmodified DSDT.
I tried also modified after fixing most errors in it. I did not understand 
what _WED should return so it was only one that remained....(reading acpi 
specification documents now)


Changing ec poll delay did not do anything, but debug.acpi.disabled=ec
strips some errors and error will stop to annoy me after system gives up 
trying to read battery.
