I have a similar problem. I wrote about 450MB of my stuff to a CD-R and
reading certain bits of the disk causes my machine to hang completely (CAD
doesn't even work). I know exact directories that will do it, and only at a
certain point in the directory. There are some files that cause the same
problem.
This is using the ncr53c400 driver, linux 1.3.latest, Texel CDROM drive.
I'm waiting on new firmware in case that is the problem but it seems from
the above mail from Angelo that it might not be.
