( This has been resend, [EMAIL PROTECTED] already got a copy as well as the usb-uhci
maintainer as listed in MAINTAINERS )
DISCLAIMER: This oops may very well be categorized in the 'user
shoots himself' department but I still thought it interesting enough
to post a bugreport and see if anything can be done against it.
So here goes.
Using kernel version 2.2.18pre9, use the following steps to get a
repeatable kernel oops:
1) Compile kernel with usb support: hid.c, mousedev.c, input.c et al.
2) Install kernel, insmod USB drivers.
3) Configure gpm to use /dev/input/mice and the attached M$ USB mouse.
(all is fine at this point, no problems whatsoever, the mouse works
like a charm)
4) rmmod mousedev.c (okay, stupid but heck I was playing around ;)
5) restart gpm
6) watch the nice oops message and laugh :)
So here it is.

How do I get rid of the warning anyway? I've never used ksymoops
before so I probably am doing something wrong here :)
And finally, for those who care to know every gory detail, here's the
syslog, including boot messages & oops. (Edited for brevity, and
probably not needed but I like to be on the safe side)
