IDE can't handle disconnects like real scsi does. The fixate command effectively locks the bus until it completes. There has been some movement forward in the standards on this.

There is much IDE to clean up first Alan - 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/
