David -----Message d'origine----- De?: Clemens Koller [mailto:clemens.koller@anagramm.de] Envoy??: mercredi 21 septembre 2005 16:15 ??: David Sanchez Cc?: Jeff Garzik; linux-kernel@vger.kernel.org Objet?: Re: How to Force PIO mode on sata promise (Linux 2.6.10) Hello, David, Jeff! > I'm using the linux kernel 2.6.10 and busybox on an AMD db AU1550 with a > hdd connected to the pata port of a PCI card (Promise PDC20579). I'm using a PDC20269 (on Promise Ultra133TX2 card) w/ DMA disabled on an embedded ppc (MPC8540). I cannot use DMA, too. I guess it's a PCI IRQ/REQ/GNT problem on my board. With DMA disabled I haven't had any problems on my system. I am going to use a PDC20275 in the future. My .config of a linux-2.6.13-rc7 is attached. And... I know other guys with similar problems on embedded environments. Unfortunately I wasn't able to have a closer look at this problem yet.
