Unable to handle kernel NULL pointer dereference at virtual address00000009

I have a lot of trouble on machines with USB disk.
Some time process which access to this disk are blocked and shutdown command don't stop the system (unable to remove usb-uhci module).

I'm using 2.4.26 kernel

Do you need more information ?

To solve my problem, is it possible to take usb module from 2.4.30 ?

Thanks,

Yves
