I had a chance to test several MBs with the same 6000+, 5000+ and 4600+ cpu

At the end seems that the problem is mb/hardware related since some 
combinations hung even with latest BIOS installed and others not.

I tested newer MATX MBs and the only one which seems to run stable for long 
time is the Gigabyte MCP61 chipset. All others are freezing sooner or later 
with Athlon 5000 or faster CPUs. 

The problem is less with the 4600 CPU almost all boards are fine and with 4200 
CPU no problem at all.

The MBs with sis vga onboard are appearently unusable with the higher freq 
CPUs. ATI and NVidia are ok. 

Xorg appearently do not like HPET enabled because it freezes then with all 
this boards I tested.


Anyway, funny is that Fedora 7 which I have on the same HD is not freezing  
(same xorg+kde version) what makes me guess that eventual there is some 
problem with freebsd's acpi understanding the acpi tables when using this 
high freq amd processors.

Only to remember the problem only ocurres when loading powerd and seems the 
freeze happens when cpu freq is upshifting not down.

Not sure if it is worth looking deeper into this on 6 and soon I have some 
time I will check current first
