2.4.17-rc2 oopses when unloading hid.o

Please CC me, I'm currently not on the list due to lack of time.

I've got two oopses when I unloaded the drivers/usb/hid.o module
('rmmod hid'). Here's the first:

Configuration is attached. Relevant things:
devfs, usb-uhci + usb core built-in, hid as a module.

And what proprietory modules were loaded ?
Can you repeat the problem without them?

They were the VMware Workstation 3.0.0 modules. Sorry, I forgot to mention 
because I had already unloaded them for unrelated reasons.

The second oops I reported is from a clean kernel IIRC, however I can 
reproduce the same oopses even without tainting modules.

Can you run them through ksymoops for us?
