"idex=ata66" parameter used to only override host side cable detection but to be able to deal with short 40-wire cables it now also overrides device side cable detection (patches were merged in Linus' tree, 2.6.23-rc1 will have them). > As it stands, I will have to run these drives at ATA33.

Please send the output of hdparm --Istdout for this drive. "idex=ata66" or CONFIG_IDEDMA_IVB=y should also help but we really would like to detect and workaround such issues automatically, without the need for user headaches. ;) Thanks, Bart - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
