Linux has a table of what amounts to various CF IDE quirks in https://github.com/torvalds/linux/blob/master/drivers/ide/ide-cs.c#L275. Among the affects it disables DMA on all of these. I have a particular device in my router, a TS2GCF133 (it isn't in their list but exhibits DMA problem) that I would like to disable DMA on. hw.ata.ata_dma="0" in /boot/loader.conf has the needed affect. Is there an equivalent way to blacklist the device by ID in FreeBSD kernel, or must this be pushed on the end user to figure out with loader.conf? Regards, Kevin
