    Now is the time for people to list their must-haves and would-likes
    for the release!  Please use this thread.  I'll start it off:

There is a bug that has been lingering for some time that I would sure like to see fixed. We have not been able to run a serial ATA DVDRW drive on any of our machines. Any time it is connected, we get continuous repeating errors like

    intr 10 at 40001/40000hz, livelocked limit engage!
    intr 10 at 19810/20000 hz livelock removed.

We have found a few past postings apparently about this issue that
suggested that the problem might be related to USB.  We have found no
other mention of the problem being related to SATA CDRW/DVDRW drives.
However, it only occurs on our machines when an optical SATA drive is
connected.  SATA *hard* drives work fine and USB works fine otherwise.  We
have tested on two different Intel machines, and an AMD64 machine, with
an add on PCI SiI 3512 SATA150 controller card.  We also tested with the
on board VIA 6420 SATA150 controller on the AMD64 machine.  The problem
exists in all cases.  We have also tested with 3 different SATA CD

The problem exists on dragonfly 1.10.1-RELEASE and we just tested today
with the latest snapshot ISO image from yesterday (07/12/2008) and it
still exists.

Could you try to install FreeBSD 7.0 (and maybe a -HEAD version as well). Just to see whether it experiences the same problems. As DragonFly inherits the (n)ata code from FreeBSD, it would be easier to locate. But I fear it's unrelated to our nata code.
