Previously VIA IDE driver ignored DMA blacklists completely (which was of course wrong), it was fixed. Probably this drive should be removed from the blacklist. Does anybody remember why was it added there?As I said before almost all of our blacklist is junk from when the IDE ATAPI DMA bug wasn't fixed.I sure don't remember why, so sounds plausible.Could you please accept this patch? (against vanilla 2.6.10-rc2) I have tested my RICOH CD-R/RW with this patch (on CD Reading/Writing), and it works just fine with DMA enabled. (Unfortunately I do not have any other drive in the DMA disabled list, and hence I could not test for them.)
