On CDs there has never been a problem. However, I put in a DVD movie disk, mount it mount -o nosuid,nodev -t cd9660 /dev/acd0c /dvdrom and then cd /dvdrom/video_ts ls which works, but then file * kills me. It gives output for a couple files, then hangs for a little bit and then -- ka-boom! reboot! Pretty frightening when a read operation on a filesystem can do that. It happened twice in a row for the two times I tried it, so, by induction, I think it will consistently happen, though I am reluctant to try this often. Looking at /var/log/messages gives me no clue at all. Is there another log which would be more disagnostic for this? I don't have another DVD to try this out with, currently. Should I just wipe the fuzz off and try again? Attached is my dmesg. -r Copyright (c) 1992-2001 The FreeBSD Project.
