This is on a Cyrix box. Full dmesg output below. DMA works perfectly fine on this box, under Windows, FreeBSD 4.7, 5.0-RELEASE, but on 5.0-CURRENT it stops working. I'm not entirely sure when it stops working, I merely cvsup'ed after installing 5.0-RELEASE a few weeks ago, and it stopped working. I cvsup'ed, made kernel and made world yesterday, and still no dma. I am guessing it was turned off on this particular board/ata controller for a reason.. And perhaps there is some way to override that and turn dma back on anyway? Thanks, Martin. Copyright (c) 1992-2003 The FreeBSD Project.
