Hi,

What kernel (test10)?
>      -m /boot/System.map-2.4.0-test10 (specified)

What compiler/version?

Please post a list of your USB devices from
/proc/bus/usb/devices .

Are you inserting or unplugging a USB device when this happens?
If not, are you doing anything with USB when this happens?

Thanks,
~Randy_________________________________________
