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
