Bug 208817

Description of problem:

This is basically a cut and paste from a recent thread on fedora-test-list.  It
pretty much cuts to the heart of the problem.

I'm having problems getting my Dell Inspiron 9300 to see my DVD-RW as a
SATA device (/dev/sdb[x]) instead of a IDE device (/dev/hdb[x]).

This seriously impedes performance of the drive.

Having done a little searching around the Internet (what a tool!) it
appears the problem may be that both the ide and ata_piix drivers are
included in the kernel as modules and that this results in the ata_piix
driver installing before the ide driver and as such the DVD-RW drive is
then seen as an IDE device.

It's suggested that the ide driver be compiled into the kernel so that
is installs first which results in the ata_piix driver then picking up
the DVD-RW drive and getting it Right(TM).

Can someone interpret what I'm saying (;-]) and then comment on how
these two drivers are included in the kernel and whether or not this
might affect the outcomes.

Alternatively, can someone suggest another fix for this.

Doesn't ring a bell, and it doesn't show up on the SATA bug tracker list..
(https://bugzilla.redhat.com/bugzilla/showdependencytree.cgi?id=FCMETA_SATA)
Though that's fallen a bit by the wayside in recent times, so there may
be SATA bugs that aren't listed on there.

It won't hurt to file a new one.
