WARNING: / was not properly dismounted.
In case it matters: the CD-ROM drive is a "SAMSUNG SCR-831", the
mainboard is an "Intel Advanced EV" with builtin audio support.
My /etc/fstab looks like this:

>Description:
The CD that I use is the second disc from "Coral Draw 5" (the one with
the fonts on it). I can mount the CD with no problem and go down into
most of its directories, like this:
shell: ls -C /cdrom/fonts/type1
a d g j m p s v
b e h k n q t w
c f i l o r u z
But as soon as I want to list the contents of the "a" or the "z" folder
my system simply freezes, no core dump, no nothing. The only three
things that still work are:
1st) I can switch between virtual terminals.
2nd) I can type control characters, but they are only echoed and don't
show any effect.
3rd) I can drop down into the kernel debugger. It reports
Debugger("manual escape to debugger")
Stopped at _Debugger+0x36: movb $0,_in_Debugger.122
and then waits for my input. I admit that I don't know what to look for
at this point.
The only way to return to normal operation is to press the reset button.
I can access these folders from MS-DOS 6.22 on the same system without
problems, so it's unlikely a defective CD-ROM or CD drive.
>How-To-Repeat:
Mount this CD-ROM and try to list the "a" or "z" folder.
>Fix:
No idea.
