ahci: attachment to atapi device

[Matthew Dillon]

:Hi,
:
:I just tested the new ahci driver on a Core 2 machine with ICH7 chipset.
:It attachs to a SATA DVD burner, which I believe should be left to the nata
:driver.
:Kernel is 2.3.1 GENERIC with SMP enabled (no apic).

    That part is correct.  The SATA DVD burner is on a SATA port.  You
    have to use cdrecord (instead of burncd) to burn via cd0.

    I'm not sure what is going on there but get the latest git and try
    again.  It will be less verbose and shouldn't try to double-ident
    ahci0.0.  I'm hoping that is the cause of the forever-repeating
    timeouts.
