Hi Antonio. Am I correct that you have a Broadcom gigabit ethernet
(bge) adapter plugged into a slow USB port, in addition to the ath
card plugged into a cardbus slot? If yes, what happens when you
unplug the bge adapter? Are you intending to run that machine as
a network bridge or router?

Hello Walt
AFAIK this broadcom gigabit ethernet is integrated into the motherboar.
This machine is a Dell Latitude D620 so I cannot unplug the bge adapter.
I am intending to use this machine as a Desktop.
Shoud I compile kernel without bge support?

'bge0/uhci3' just means those two devices share the same interrupt vector.

My guess is, the card actually lives at IRQ 5, and not where DFly thinks
it's living (which would be on cbb0).

I report that booting with ACPI disabled goes fine and the system don't
spit out that message.

Is the machine working properly now, including the ath card?
