I later discovered that there is a change with respect to shutdown-functionality between 2.6.28 (on which I made the driver) and 2.6.31. I have to update the driver to 2.6.current anyway. > I think that this driver should replace current ark3116 driver. Having two > drivers for the same hardware is a bad thing. I agree. However, given the experimental nature of the driver, I would prefer some more testing. Then again, the original driver is lacks some features, and making ark3116new default would increase its exposure ;-).
