If you want to play with failed devices I'd suggest the best test device to work with is actually something like the SIL680 with shared address setup. I've been watching the changes so far and the overall direction looks right to me. As far as I can see from the PATA side of things the "we care about another horked device on the bus" situation is a) Extremely rare (I've almost never seen it on drivers/ide reports) b) Usually a controller programming screwup (so wants fixing there) c) With very few exceptions needs no special handling. I can find no case where a set mode failure followed by a switch to PIO 0 on the controller for that device (which is right - the device didnt switch so its in the old mode....), doesn't do the right thing.
