USB module crash

[Manuel Hartl <mhartl@hartl-it.de>]

hi list,

last night (i think again) usb module(s) crashed. the running usb 
devices are a avm fritz usb dsl 2 and a usb mouse. i do not think this 
is avm related (cdslusb2 module), maybe an acpi/power management error?

please loook at the included stack trace.
can someone tell me (by looking at the trace), what could be the problem 
here?

hardware:
asus a8v deluxe (via k8t800 chipset) / socket 939 / amd64 3000+
cool and quiet was active in bios, but no module was loaded 
(powernow_k8), acpi/apic is enabled.
