Alright, than it eventually is a kernel-issue. I installed the kernel-image-2.6.8, because it was (is still) the newest in debian-testing. Will burn cds as root for a while now, don't want to compile a kernel right now. Thanks for the tip about looking at K3b website and for kernel bugs. I was always searching in mailing-list and wrote a mail if I didn't find a report about that problem. Wolfgang -- +++ NEU: GMX DSL_Flatrate!
