Same here. 3 computers with PIIX4, 2 (or maybe even 3, need to check the 850M Conner too) different disks (all pre-udma but mwdma, 2.5G Seagate Medalist and 850M WD Caviar). The common denominator seems to be PIIX chip (PIIX3 and PIIX4 reported so far) and multiword DMA. It came with 2.4.19 for me - 2.4.18 (and thus also Debian Woody) is fine but anything with a newer kernel (incl. 2.6.*) is broken - DMA timeouts. So maybe it is a little different (since your 2.4.20 works) but still very similar. -- Meelis Roos (mroos@linux.ee) - 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/
