DVD drive stopped working couple of months after upgrading to Fedora Core 8

Hi All,

Been a while since I've actually asked a question but I'm stuck!

I recently upgraded to Fedora Core 8 which ran perfectly fine for a couple of months but then suddenly started giving me trouble.

My DVD writer is a Pioneer DVR-212. I've been using this drive for a while now mostly with Core 7 with no dramas at all. When I upgraded to Core 8, as I said above, it worked fine for a little while but all of a sudden it stopped working, must have been something I did but I've got no idea what!
I also have an extra non-system hard drive in the same PC with several partitions on it for general storage that I mount manually when ever I need it. At about the same time that the DVD drive stopped working the system started mounting all the partitions on this drive automatically at boot, creating dir's automatically in /media where these partitions get mounted to. I have no idea why this started to happen! I only want these partitions mounted when I need them. I've looked everywhere I know but I just can't find how to disable this!

Below is the output from "dmesg | grep ata1" (ata1 is the DVD drive) & a brief description of my hardware. Most of the dmesg output is also displayed at boot just before init starts & causes about a 5 minuet delay before the rest of the system boots, obviously this really sucks!

I've done a fair bit of Googling but haven't been able to find the answer to either of these issues.
I hope some of you Linux Geniuses out there can help me!

i do not use F but automounting ....check your /etc/fstab....if it has no entries for dvd or cd.....good....but if you see auto in the line...with root powers change that to
noauto.

2) it may also relate to the HAL daemon.

3) can you use a normal live cd in dvd drive? if so you hw is not failing so its Fedora.

you may wish to submit a bug?

Thanks Mate! Sorry for the late reply.

I duel boot with Windows & the drive works under that so it's defiantly not the hardware.

I'm pretty sure it has something to do with HAL as all the other drives started automounting at the same time that the DVD drive started playing up. I know nothing about HAL so guess I'll just have to do some reading.

Perhaps it is a just bug & hopefully it'll be fixed in FC9.

So unless you've got any other advice, thanks for your help.

I had some similar problems, with a errors continually posted in my /var/log/messages such as:
"Mar 7 20:03:35 fedora kernel: ata3: soft resetting port
Mar 7 20:03:36 fedora kernel: ata3.01: configured for PIO0
Mar 7 20:03:36 fedora kernel: ata3: EH complete
Mar 7 20:03:46 fedora kernel: ata3.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen
Mar 7 20:03:46 fedora kernel: ata3.01: cmd a0/00:00:00:00:20/00:00:00:00:00/b0 tag 0 cdb 0x1e data 0
Mar 7 20:03:46 fedora kernel: res 40/00:03:00:00:20/00:00:00:00:00/b0 Emask 0x4 (timeout)"

The "soft resetting port" is what is similar to your errors. Basically I would have my DVD accessible for about 5 mins after each boot, and then just start getting the above errors. Anyway, I fixed by adding a kernel argument:

pci=nomsi

...and I have not had any issues since. Now it is not exactly like your error, because I was having the same issue all throughout Fedora7 too (basically I was booting to Vista for any DVD reads for about 6 months), but give it a shot.

Thanks Mate.

Sorry I took so long, only just noticed your reply.

I tried what you said but unfortunately it didn't work! I just hope that it is fixed in FC9.

yes it could be hal but I am now thinking its udev and you will find udev rules in your /etc/
