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

Was hotplugging enabled at the time, or is this message wrong?  If the
message is accurate, I would expect an Oops, the same way you often get
an Oops if you unplug any piece of hardware that's not hot pluggable
(assuming the hardware survives).

Can you try 2.6.8-rc4 to see if this is fixed there or not?

And did you unmount the camera after mounting it, before removing the
device?

thanks,

HI Greg,

I tried the 2.6.8 kernel and my USB camera is working much better - perfectly, 
in fact! 

Thank you very much!
