Eh? The whole point with that patch was to ADD ADMA support to sata_nv, imho that is something we want to have and i have been running with ADMA on on two computers since sata_nv-adma-ncq-v4 or 5 or so without problems. So, something has been introduced or been broken to cause this error, wouldn't it be better to find the error introduced than to just totally negate the patch in the first place? I haven't had the energy to go trough the patch that was found as causing the problem yet... I don't know if i even have all the info needed to make any form of educated guess but i'll give it a try when i have the energy. I really home someone finds it before then =) -- Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net
