I have a Maxtor 160GB drive as master on one channel, and an IBM 40GB as master on the other channel, so I'm not using raid in any form. I'm using both 2.4.21 and 2.4.19 with this hardware... - From dmesg: CMD680: IDE controller on PCI bus 02 dev 48 CMD680: chipset revision 1 CMD680: not 100% native mode: will probe irqs later ide2: BM-DMA at 0xe8c0-0xe8c7, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0xe8c8-0xe8cf, BIOS settings: hdg:pio, hdh:pio ... hde: 80418240 sectors (41174 MB) w/1863KiB Cache, CHS=79780/16/63, UDMA(100) hdg: 320173056 sectors (163929 MB) w/2048KiB Cache, CHS=19929/255/63, UDMA(100) I wonder if the fact that the bios is setting PIO is the clue here, and you shouldn't be using dma on them, even though the drives are DMA...? (I get confused by the discrepancy between what the controler reports and what the drives report, so I'm winging it a bit here) Mark. - -- Mark Watts Senior Systems Engineer QinetiQ TIM St Andrews Road, Malvern GPG Public Key ID: 455420ED -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (GNU/Linux) iD8DBQE/HphoBn4EFUVUIO0RArOkAJ4hvJCdBZ6BtjujEWY3ok4mwsqqbwCfe2oo EL5ddn5xyk9jbGIf3GSLxaw= =OCD7 -----END PGP SIGNATURE----- - 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/
