I got the attached oops when copying a file from a SVCD using cdfs-0.5c
I mounted a SVCD using
mount -t cdfs /dev/cdbrenner /cdbrenner
using the cdfs driver from
http://www.elis.rug.ac.be/~ronsse/cdfs/cdfs.html
and then copied one of the files on the CD with
cp /cdbrenner/videocd-1.mpeg ~/film.mpg
after some time (copied file size is 168996864 bytes while original file
size is 820799616), the oops happened.
Kernels is a self compiled vanilla:
Linux version 2.4.20 (root@Knoppix) (gcc version 2.95.4 20011002 (Debian
prerelease)) #1 Tue Dec 31 15:23:18 CET 2002
Target filesystem is ReiserFS, but it happened with Ext3 as well (just
switched to ReiserFS to make sure it isn't the Ext3 code).
The CD-ROM is an ATAPI-CD-writer
lobo:~# cat /proc/ide/hdc/model
HL-DT-ST GCE-8320B

lobo:~# cat /proc/scsi/scsi

This is my current list of modules but I did only do a reboot. The
'tainted' comes from the nVidia driver, but it wasn't loaded when the
oops appeared, i.e. the kernel was not tainted at this time. Also there
was no ppp module etc.
