Subject: Unable to write dvd+r on 3 systems

Resend due to crappy formatting, sorry about that!

It seems I am the last person on earth burning dvd's. I have tried on
three different systems, using a mix of growisofs, xfburn, brasero and
k3b. They all give the same result for their respective system.

On system 1 it takes forever to complete the process. The system is
completely useless while burning. IO wait is 50% and hardIRQ is
10-20%. If audio is playing at the same time it stutters in a way that
it sounds as it's playing slow. Mouse cursor jerks and it takes eons
to even open a new terminal.

On system 2 growisofs will try for half a minute and then fail with a
message in dmesg. The disc isn't even touched. Tried homebuilt
kernel.org kernels from 2.6.25 to current git with no difference. See
attachment "growisofs_system2.txt". I have been able to burn exactly 1
disc in total, which magically started recording immediately.

System 3 burns at decent speed and always reports success, but about
half the time only part of the disc is actually burned. It is visible
to the eye, and it will not work. Tried at 4x too.

I tried to compile older kernels, 2.6.24 wouldn't boot, and older
kernels would not compile on these systems.
