growisofs - 2 x Sony DVD RW DRU-700A - Error leading to kernel panic
I am trying to burn two DVD's at once on two USB Sony DVD RW DRU-700A burners using growisofs. It seems that part way through the burn something went off the rails and eventually caused a kernel panic. I have successfully done a small burn (900M) to a single DVD burner. Anybody have an suggestions as to what might have caused this and what I could do about it?

There was similar log output from the other burn which was started with the command line:
growisofs -dry-run -v -iso-level 2 -Z /dev/cdrom1 -R -J /u/apps/dbarchives/dvd_archive/buffers/3
But it's log does not have the final error messages in it so I presume it was happy up until the kernel panic.

This was followed by a kernel panic, unfortunately the machine was reset before i could record the details of this, all I can say is that there was a "null pointer" error message.
