Finally managed to get a nice panic:

panic: kernel diagnostic assertion "fn[fnlen] == 0" failed: file "../../../../fs/cd9660/cd9660_util.c", line 110

This was with an i386 kernel from today's code, DEBUG, DIAGNOSTIC, 


    /* fn should always contain standard C string, and wget() needs it */
    KASSERT(fn[fnlen] == 0);

The CD I was looking at had been created on MacOS X - I don't know what
flags it used.. (I think that is irrelevant assuming it's the same error
as on another computer with another CD I created with mkisofs -l -J -R -L)

Thoughts?
