TCQ shouldn't be enabled > when there is other device on a channel? Correct, that needs a check. It should work, but is far from optimal both from the software and hardware point of view...

That way I don't have to deal with the ide tcq stupidities. -- Jens Axboe - 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/
