I don't know. kded, which caused the oops, is always running. It is a KDE daemon
that polls device state and so on. So yeah, it might have accessed the drive
while growisofs was writing to it.

However with "accessing" I mean the DVD drive motor was spinning up and down
and the laser lens was moving like crazy. The sound that happens, if you put
a completely scratched DVD into the drive and it is unable to make sense of it.
However, this was not scratched. It was a new DVD with one session on it that
I just burnt 5 minutes before that. So I wanted to append another session to it
and it crashed and resulted in IO errors in growisofs.
