I'm not talking about disabling all functionality for partcular chips. It would be sufficient to disable in wd DMA/UDMA support for chipsets already supported by ata, which will encourage all users with these chipsets to use ata (while in case of any problems they still will be able to fallback to wd though it would work somewhat slower). -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
