What do you expect w/ removable media.
Obivious it has to be reporting an media status event change.
Gawd knows where I could find a copy of the hardware to verify.
If it puts a patch of mine on it and it is still present there is a
problem, if it goes away with the patch, the kernel should take the patch.
