Hi,

At least the first part of my theory i can test myself.
Not easy to find a non-32-KB-aligned image among the Debian ISOs
for amd64 or i386. That's because they are aligned to cylinders
of 1 MB for the isohybrid stunt on USB stick.
debian-7.4.0-mips-netinst.iso has 6599.4375 * 32 KB of size.
I blank a 2x DVD-RW (quick and thus usable for DAO only):
$ xorriso -outdev /dev/sr1 -blank deformat_quickest
and make a try
$ growisofs -use-the-force-luke=dao -Z
/dev/sr1=/dvdbuffer/debian-7.4.0-mips-netinst.iso
...
/dev/sr1: engaging DVD-RW DAO upon user request...
/dev/sr1: reserving 105591 block, warning for short DAO recording
/dev/sr1: "Current Write Speed" is 2.0x1352KBps.

:-( write failed: Input/output error
/dev/sr1: flushing cache
/dev/sr1: reloading tray
So this would be a bug against dvd+rw-tools.
Subject: Old growisofs error unveiled by new more picky kernel.
Nobody at home, though, except myself as neighbor and bystander.
First we need to test the remedy. (Tomorrow. It's past midnight
in subtropic germany. Crickets and cicada have a party.)
Next we need a Debian Maintainer to apply the patch.
(And if i get to catch a DM:
Subject: Please bump libburn, libisofs, libisoburn, cdrskin, xorriso to 1.4.0
)
Have a nice day :)
Thomas
