ATA driver (atapi DMA).. To: current@freebsd.org Date: Tue, 31 Aug 1999 14:13:16 +0200 (CEST) X-Mailer: ELM [version 2.4ME+ PL43 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG A little while ago I enabled DMA on atapi devices, and while this generally is a good thing (CPU usage wise), there seems to be some delicate problems with this on some chipsets and devices. If you use the new ATA driver and has atapi devices that use DMA could you please check that they are working correctly (ie try reading a CDROM two times and compare the results), and mail me the outcome of that.
