It was a problem with DMA. Someone from my local LUG suggested booting
with ide=nodma as a boot parameter and I found that the cd-rom would
work without a problem.
What I finally did:
Made a one-line executable in /etc/init.d:
/sbin/hdparm -d0 /dev/hdc
Added a symlink for that to /etc/rcS.d/
The hard drive I'm using can handle DMA, of that I'm sure, so I thought
it would be better to keep it as such as it is so much faster.
I came across a very nice reference during my search for info:
