I installed the kernel update which was available. I decided before
detaching the cd-rw drive to just boot the system with the new kernel
(2.4.22-1.2188.nptl) and see here my messages from dmesg:

So problem solved with the new kernel??
(I can not find any evidence in the release notes of the kernel update to
second that...)
