IO errors when inserting a disc

[Simon Morgan]

On inserting a disc into my DVD-RW drive, I very often got some serious looking I/O errors in the kernel logs. At first I put this down to hardware failure and bought a new drive. However, I not only have the same problem with the new drive, but the way the problem manifests intself leads me to believe it could possibly be a kernel bug. The old drive was a Pioneer DVD-RW DVR-108 and the new one is a Pioneer Pioneer DVD-RW DVR-116D.

The errors only appear when I insert a disc into the drive. Not only that but I can do things like playback DVD movies and read entire discs (I tested using dd_rescue) without a single I/O error appearing in the kernel logs.

The type of disc also has a bearing on the problem.

If I insert a data DVD into the drive, I don't get any errors.
If I insert a video DVD I get the following kind of errors:

[ 3130.194461] end_request: I/O error, dev sr0, sector 16039324
[ 3130.248798] end_request: I/O error, dev sr0, sector 16039320
[ 3130.302954] end_request: I/O error, dev sr0, sector 16039328
[ 3130.303145] UDF-fs: Partition marked readonly; forcing readonly mount
[ 3130.398541] UDF-fs INFO UDF: Mounting volume 'ADAM_AND_JOE', timestamp 2006/03/09 09:54 (1000)

If I insert a data CD into the drive, I don't get any errors.
Audio CDs give the following error:

[ 4267.245458] end_request: I/O error, dev sr0, sector 0
[ 4267.245477] Buffer I/O error on device sr0, logical block 0
[ 4267.245486] Buffer I/O error on device sr0, logical block 1

[ 4267.245527] Buffer I/O error on device sr0, logical block 6
[ 4267.245533] Buffer I/O error on device sr0, logical block 7

I think this may have to do with the dialog that pops up when I insert a disc into the drive (the one that asks which program you want to launch), or something related to it. It seems that whenever that dialog appears, I get the I/O errors. Maybe whatever is scanning the disc to detect what type it is is doing something weird, resulting in the errors?

[Rob Watson (r-watson)]

I can confirm this with Kubuntu 8.10 (kernel 2.6.27-9-generic #1 SMP). When I insert an audio CD, I get the following errors appearing in /var/log/syslog:

kernel: [ 4303.501495] end_request: I/O error, dev sr1, sector 0

kernel: [ 4303.506337] Buffer I/O error on device sr1, logical block 0

This did not occur prior to upgrading Kubuntu from 08.04 to 08.10, and does not occur currently with the same audio CD and same drive with Ubuntu 08.04 (nor with Windows XP). The same thing occurs with my other CD/DVD drive on the same machine (with sr1 --> sr0).

Nothing pops up on the UI at all.

[Dovel (dov01)]

I can confirm this on Ubuntu Intrepid, running all the latest updates as of 19/12/08. My main issue is when trying to mount cd's with image files on them. Have to mount them from the terminal, and then it still takes a minute or two to mount. Will post more in the morning.

[Dovel (dov01)]

As written above, my main issue is with CD-R's with images stored on them. It seems that they all use the Joliet format. Have attached excerpts from my dmesg and kern.log

[BenM (benmottram)]

I can confirm this is an issue with Hardy Heron on a Dell Latitude 610. The internal DVD drive will play audio CDs no problem, however when trying to play a DVD (Correct region, works fine in Windows XP ;) ) I get the buffer errors in dmesg:-

[ 160.488507] UDF-fs: Partition marked readonly; forcing readonly mount

And both VLC and the default media player will not play the movie.

[Simon Morgan (sjmorgan)]

BenM: I don't think that's the same problem.

I didn't have the problem with Hardy and my drive can play/read everything fine which leads me to believe that the errors are spurious. It seems that they aren't in your case and there may be a genuine problem with your hardware (or maybe you don't have libdvdcss installed).

[BenM (benmottram)]

Hi,

My bad all, it was the libdvdecss issue - one would have thought that
the software could detect the lack of libdvdcss or equivalent, however
that may be tricky politically or legally.

I had a similar issue on a LiveCD burnt with Debian Lenny -- it gave the Buffer I/O errors on sr0 when booting the LiveCD. I thought initially it was a kernel issue with Ubuntu 8.10. Writing/Reading a DVD did not give the errors, nor writing the iso image onto a USB stick. Following the instructions in http://www.troubleshooters.com/linux/coasterless.htm I burnt another CD with the same iso image. This CD did not have the buffer I/O sr0 errors. So, it's possible that adding the "padsize", "-pad", and "-dao" options to "cdrecord" solved the issue for my CD/DVD drives. (cdrecord dev=0,0,0 speed=10 blank=fast padsize=63s -pad -dao -v -eject)

Might be related to bug #321174 .
Could you people affected by this defect check wether you can get a blank DVD to be properly recognized ?

I have the same issues.

[Rob Watson (r-watson)]

The same problem is still present in Kubuntu 9.04 (kernel 2.6.28-11-generic).

[kernel-janitor (kernel-janitor)]

Hi Simon,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 304954

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Christian Neumair (chris-gnome-de)]

This is very likely a duplicate of bug 459316, which I just opened with a similar issue. I probably found the reason:

It happens when you have fast devices (UDMA-66 or later) and an IDE cable only supporting UDMA-33 reliably (40 pin instead of 80 pin). Linux seems to configure the devices for UDMA-66 or later (in my case even UDMA-100), and this causes transmission errors with the old cables. Linux should however only configure the devices for UDMA-33 max with a 40 pin cable.

[Rob Watson (r-watson)]

My kernel (Kubuntu 9.10, kernel 2.6.31-14-generic) appears to already be treating it as UDMA/33. From /var/log/syslog:

Not sure how this fits with your idea. Is there somewhere else I should be looking to confirm or disprove?

Are you using brasero? Its CD images burned produce kernel I/O errors with some optical drives.

[Rob Watson (r-watson)]

I'm using audio CDs bought from a shop (remember them?) that are 'pressed' in a factory, not burned, so I don't see how Brasero can be the culprit.

[Alroger Filho (alroger-filho)]

I think it's something with Brasero and/or Nautilus/GNOME. K3B just works, while GNOME doesn't even detect that I've inserted a blank disc.

This problem still persists in Ubuntu 10.04. I attached the apport data.

[alex_b (barth-alexander)]

I tested the DVD in windows and it works there. Therefore, I don't think that there is a problem with the DVD.
