Does the SB700 have the same limits as the SB600 on 256 sectors in one PRD entry ? If it does then this change needs to wait until the workaround for that is included. - To unsubscribe from this list: send the line unsubscribe linux-ide in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Thanks for the reminder, but that issue only appears on SB600, while SB700 does not have that limitation. I'll submit this SB700/800 patch again with a private mail box later.
