I got the following errors and back-trace upon mounting my IDE CD-ROM
(hdc).  It seems to be a normal ISO9660... its the Red Hat 9 CD.

I haven't looked into it yet.  Not sure why there is ext3 stuff in
there... maybe the CD-ROM mount is unrelated?  Mounting the CD
subsequent times is OK.

Kernel is 2.5.66-mm2.  UP, preempt, no highmem, i686.

Here we go:
