wodim fails to burn DVD+RDL

[James Finnall]

I use K3B to burn DVD's for longer than I care to think about. I just upgraded to 11.10 with kernel 3.0. All dual layer burns have failed since the upgrade. I have been able to complete a dual layer burn properly by booting the prior 2.6.38 kernel from 11.04. Below is the tail end of the log report from k3b using wodim 1.1.11. I was able to burn a single layer DVD normally with kernel 3.0.0, but it might use another program to burn with.

cdrecord command:

On all of the failures since my upgrade to 11.10, this error has been the same as above.

/usr/bin/wodim: No such device or address. Cannot send SCSI cmd via ioctl

Now that is unusual since it just completed burning almost 8 GBytes of information also indicated above.

Something unusual with this problem is that a single DVD burned and completed normally. Unfortunately I did not view the report to see if it used wodim or other package to burn with.

The program wodim 1.1.11 is over a year old so I do not suspect that is where the problem, unless there was a change in the version 3 kernel that would effect it. It could be a compile issue of the version 3 kernel as well.

Thank you for the assistance. For now I will just boot the 2.6.38 kernel.

You are not using the official software but a copy from 2004 where the working
DVD support was ripped off and replaced by some thing half baken. I recommend to
upgrade to recent original software from:
