Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 994 Lines: 25 I'm using 2.6.16-rc6-ide1 (alan's patchset) and using the sata_nv and pata_amd drivers. I have all UDMA drives except a CF disk -> IDE interface, which should be running in PIO mode4. Libata detects the device, but spits out a message about "no dma" and then says it's not supported and is ignoring it. Is this device not supported because it's not using dma or for some other reason? It's the only device on it's channel (secondary pata) ata6: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xF008 irq 15 ata6: dev 0 cfg 49:0e00 82:0000 83:0000 84:0000 85:0000 86:0000 87:0000 88:0000 ata6: no dma ata6: dev 0 not supported, ignoring scsi5 : pata_amd I'd really like to get this up and running so if anyone has any suggestions, I'm all ears. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
