Looking at the important piece: ----- > + /* Always use 4 address setup clocks on ATAPI devices */ > + if (drive->media != ide_disk) > + t.setup = 4; ----- it seems to me that using 4 for t.setup also should be done unless _all_ devices on that cable are ide_disk. In particular, if one device is ide_disk but the other is not, then "t.setup = 4;" should be used even when talking to the ide_disk. Otherwise the non-ide_disk device might get confused, respond when it should not, and garble the transaction. Or, is such a bad thing prevented in some other way? -- John Reiser, jreiser@BitWagon.com - 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/ | ||||||||||||
