[1.] Summary of the problem
===========================
rmmod hangs when I do 'rmmod usbcore'
======================================
[2.] Description of the problem/report
======================================
I want to try 2.5.62, so I compiled it w/modules support. Booted OK.
Doing 'modprobe hid' I get the modules 'usbcore' and'hid' loaded
(but the usb keyboar doesn't work).
Doing 'rmmod hid' everything is OK, but doing
'rmmod usbcore', the process 'rmmod' hangs, and
doing 'ps aux' show this:

I'm using the keyboard with NO problem on
2.5.59-mm2, but usb support compiled into kernel, NO modules support at all.
