I'll give your partial revert a try. > Alternatively you can try using the pata_cmd64x.c driver instead :-) Well, that's not yet available in current Debian kernels. I did test pata_cmd64x once (way back in July 2007, when Alan Cox requested it), but have not used it since as I normally run distro kernels on the box. When I build the custom kernel with your patch I'll activate it and give it a try again. Thanks, FJP
