Stock FreeBSD 5.3-BETA7 ISO Disk 1, i386
>Description:
FreeBSD is disabling the fan causing the system to overheat and shutdown. 

hw.acpi.thermal.tz0.active=0
>How-To-Repeat:
N/A.
acpi0: <COMPAQ RSDTBL> on motherboard

>Fix:
set hw.acpi.thermal.tz0.active=1 in /boot/loader.conf and reboot, but then the fan is always on (unless you manually set hw.acpi.thermal.tz0.active to 0). the other option would be to disable acpi.

 I'm not sure if this will help but I found a linux kernel patch that 
 claims to fix the ACPI issues with the Compaq Armada 1700 and 1750

 As requested, here is a copy of my ASL:
 http://www.nbritton.org/uploads/compaq/armada_17xx.asl
 
 This bug also affects the whole Armada 1700 series.
 
 The work around I submitted does NOT work if the system is below the 
 hw.acpi.thermal.tz0._ACx threshold, if it is below this threshold at 
 system boot the fan will NEVER turn on even if 
 hw.acpi.thermal.tz0.active=1 is set in loader.conf.
 
 Also is it possible to just extract the AML code from the Linux patch an 
 use it to make a FreeBSD patch? I don't know as I'm not a programmer and 
 I'm not sure of any GPL issues.

 Is this still an issue?
