Actually we've had the CX700 supported for a while and as Tejun has fixed other bugs related to it we know its being used and tested. The slave port is a bit quirky but that is purely in the way it seems to mess up the snooping of mode changes. Yours is the first bug report of this type so more information about the precise combination of devices used and the actual logs would be useful. > It builds fine and seems to start up OK, however, on large IOs then > the kernel starts to throw errors about MULTICMDs (I think that was > the term) returning an invalid response. No thats not a term I can guess at - do you have any logs with the exact error reports in them ? Also unfortunately you've compared 2.6.23 with 2.6.24 which means a bug anywhere else could be causing the behaviour you see. It would be very interesting to know if 2.6.24 built with old IDE rather than pata_via (which is just config options) shows a difference in behaviour on your box.
