HI everybody,

When I unplugged my Kodak DC4800 USB camera, I noticed this kernel problem 
in /var/log/messages.  I'm running a stock 2.6.7 kernel compiled for SMP.  
The problem is reproduceable.  Please cc me on any replies, and let me know 
if I can perform experiments, etc. to help isolate this problem.

Thanks!

Andy
