Oh, and forget TCQ. It's a completely worthless technology inherited from PATA, whos continued existence can only be explained by some companies having invested money adding firmware support for it already and/or because it sounds good to marketing who apparently rely on customers thinking it must be similar to SCSI TCQ because it shares the same name. In reality, they really share nothing. IDE TCQ makes a mockery of the TLA, I hope the people that came up with it bury their heads in shame for having wasted peoples time actually tring it out. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
