See http://lkml.org/lkml/2006/5/23/198 for instance - IIRC, the kernel has no way of telling whether the failure is because the card supports DMA and the adapter doesn't, or whether the card is lying. If it's the former, the card shouldn't be blacklisted. -- Matthew Garrett | mjg59-chiark.mail.linux-rutgers.kernel@xxxxxxxxxxxxx - : send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
