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: # Device Mountpoint FStype Options Dump Pass# /dev/wd0s2a / ufs rw 1 1 /dev/wd0s2b none swap sw 0 0 /dev/wd0s2b /tmp mfs rw,-s=32768 0 0 /dev/wd0s2e /var ufs rw 2 2 /dev/wd0s2f /usr ufs rw 2 2 /dev/wd2e /usr/obj ufs rw 2 2 /dev/wd1e /home ufs rw 2 2 proc /proc procfs rw 0 0 /dev/wcd0c /cdrom cd9660 ro 0 0 >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. -- Sascha Blank | "I prefer to work behind the scenes.
