Description Rodd Clarkson 2006-10-02 06:55:17 UTC
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..
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.


Version-Release number of selected component (if applicable):

Current kernels in rawhide and fc5

Does the current boot.iso detect drives correctly ?

Comment 2 Rodd Clarkson 2007-06-04 09:41:44 UTC
Everything worked great with the F7 installer, so I guess it works correctly now.

Thanks for addressing and fixing this Dave.

Comment 3 Bug Zapper 2008-04-03 18:23:46 UTC
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.
