FC4 -> FC6 dvd writer not detected

[Douglas Phillipson]

After I upgraded to FC6 my DVD writer was no longer detected, I suspect 
because I had to comment out a line in /etc/udev/rules.d/50-udev.rules 
to get my machine to boot.  What can I do to get the DVD detected and 
the device made for it, after the machine is booted.  Because I had to 
comment out the following line in 50-udev.rules:

ACTION=="add", SUBSYSTEM=="?*", ENV{MODALIAS}=="?*", 
RUN+="/sbin/modprobe $env{MODALIAS}"

I had to put: "/sbin/modprobe snd-emu10k1"  in /etc/rc.local for my 
sound card driver to be loaded.  I assume I need another modprobe 
command for my DVD, I just don't know what it is...

Thanks

I've tried to ask about this problem several times, each in a different 
way, but gotten no response. Am I asking a dumb question, or giving 
insufficient details of my problem?  I'm really stuck here, any advice 
on how to troubleshoot this issue will be greatly appreciated...

Thanks

I did a search on env Mod alias and ended up with many hits. Most refer 
to modprobe. I have no idea but wonder if the reference to running out 
of memory with certain devices is causing you the problem. I'd 
investigate why it is hanging and try to get this normalized to normal 
scripts. Maybe more memory or something might help overcome the problem.

2 Questions....

1.  Is your DVD writer an internal ATA or an external USB device?

2.  If the answer to 1 was ATA, have you checked /var/log/dmesg looking for
what comes after "Probing IDE interface"?  If the answer to 1 was USB, have
you tried booting without the device attached and then doing a "tail -f" on
/var/log/messages to see the systems reaction to the event.

It's an ATA, but I don't think the device is the problem.  I noticed 
that FC6 doesn't provide both a non-smp and an SMP kernel anymore, at 
least on my dual Athon mobo.  Should it?  Do I perhaps have a wrong Kernel?

Here is the last few lines of dmesg output when booting with the 
modprobe enabled:

There is no separate SMP kernel in FC6.

It sounds as if the system is coming up, yes?  What does "uname -a" show as
well as "cat /proc/cpuinfo".

Yes...the boot process is detecting the existence of the drive.

I don't know if your DVD issue is part of this, but this bug has been
reported in multiple bugzilla entries.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=214402

is one of the entries.

Seems to be about right....

What is the output of "lsmod"?  Also, "cdrecord -scanbus".

OK...

Well, both ide_cd and cdrom failed to load.

What happens if you now try:

modprobe ide_cd
modprobe cdrom

Do they get loaded?

Ah yes!  The modprobe ide_cd did the trick.  Thank you!  I will have to 
put this in rc.local.  I wish I understood why I had to comment out the 
modprobe in /etc/udev/rules.d/50-udev.rules which causes me to have to 
put a bunch of these modprobe lines in rc.local...

Thanks again

I believe my "modprobe" problem may be linked to my Quad savage4 Video 
card.  How do I exclude a module from being loaded by udev?  I guess I 
could rename the .ko file but I would like to know how to get udev to 
exclude a driver.

Thanks

I also had problems with FC6 not detecting my DVD-writer. Turned out
that this was caused by the line "options ide-cd dma=1" that I had put
in /etc/modprobe.conf  I removed that line, and the DVD is now found and
/dev/dvd-files are created.

Not sure this is your problem, but could be one thing to check.

It turns out that FC5 and FC6 must have a gorked up S3 Savage4 video 
driver.  In the debugging output, I noticed the savage4_smbus was shown 
just prior to the crash on boot.  I renamed the driver (i2c-savage4.ko) 
to i2c-savage4.ko.orig and the machine booted just fine.  The Xinerama 
feature with multiple screens seems to work just fine without the driver 
so I don't know what the driver actually did for me.
