Comment 84 for bug 228624

I have the same problem and trying to test the various workarounds suggested here.

The problem on my laptop (asus a6k) emerged after 8.10 -> 9.04 upgrade. I though my burner was broken, and replaced it with a brand new one. Still same errors and problems.

I cannot burn anything :/

This is booted with all_generic_ide=1:
