OK, I don't want to rule out a software problem. However, I would advise to use
Taiyo Yuden media if you still can those. Those are usually those with the highest
quality and reliability.

I had another idea after I replied your last mail and I think one possible culprit could
be xorrisofs which was used for building the ISO image instead of genisoimage which Debian
used in the past.
I can actually create an installation image with genisoimage instead and you can test it.
Also, let's pull Thomas Schmitt from libburnia upstream who might know more.

Yes, it will be merged. No worries. Hopefully later this week. I didn't have the time for
a rebase yet.
