What would be nice (and I seem to recall that Andre also pushed for

the big machine uses. That other OS had a differing opinion of what to
do with that, so...

Preach on, brother Jens :)

I think we already lost this one, I'm afraid :-)

I agree completely. Or, the ATA guys could use SCSI's ordered tags / linked commands.

Regardless, there's ATA dain bramage that needs fixing... Sigh.

Indeed, and it really hurt that they passed up this oportunity last
time, ATA TCQ would have kicked so much more ass... Maybe Eric can beat
some sense into his colleagues.

I bet if we can come up with a decent proposal, with technical rationale for the change... that could be presented to the right ATA people :) It's worth a shot.
