This is the first time I have used my DVD player on a DVD and not
a CD. 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.
