[Bug 879510] Re: wodim fails to burn DVD+RDL

[Schily]

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:

 ftp://ftp.berlios.de/pub/cdrecord/alpha/

Title:
  wodim fails to burn DVD+RDL

Status in “cdrkit” package in Ubuntu:
  New

Bug description:
  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.

  Track 01: 7294 of 7297 MB written (fifo 100%) [buf 99%] 4.3x.
  Track 01: 7295 of 7297 MB written (fifo 100%) [buf 99%] 4.1x.
  Track 01: 7296 of 7297 MB written (fifo 100%) [buf 99%] 4.3x.
  Track 01: 7297 of 7297 MB written (fifo 100%) [buf 99%] 4.1x.
  Track 01: Total bytes read/written: 7652487168/7652487168 (3736566 sectors).
  Writing time: 1442.171s
  Average write speed 3.9x.

  cdrecord command:
  -----------------------
  /usr/bin/wodim -v gracetime=2 dev=/dev/sr1 speed=4 -sao driveropts=burnfree -data -tsize=3736566s -

  
  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.
