well it look's like there is a problem in the isofs code, I have this in
my /var/log/messages:

Now it's the second Red Hat CD.

Huh ? KERNEL STACK CORRUPTION ? shutdown now ;)

Playing safe, booted with No CD to avoid the problems ;)

Ok, try annother CD, this time MS's PLUS! pack CD.

Back to Red Hat Linux 3.03, March 96, Disk 2.

Hmm, there was a totaly ok mount in here (umount /mnt/cdrom; mount -o norock
/mnt/cdrom), I think only because I didn't eject the CD

annother umount /mnt/cdrom; eject; <push back in ;)>; mount -o norock
/mnt/cdrom, so it's not the rockridge stuff, has to be in something
that's done when we don't know that the CD is the same (ie it's been
ejected, you don't have to actually change the CD).
