Kernel 2.5.47-xfs[cvs] Oops when mounting ISO image.

Firstly, this is truly a terrific kernel(for me), fixed alot of stability issues I had.
Have to wonder why keyboard/mouse support is so well "hidden" though =)
Anyway, my issue is a 'oops' whenever I mount a ISO image file.
(I have compiled the loop device as a module)

example :
spam michael # mount -o loop stuff/linux-cd/knoppix/orig/KNOPPIX_V3.1-08-11-2002-EN.iso /mnt/iso
Then It becomes a zombie.

ksymoops 2.4.8 on i586 2.5.47-xfs. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.47-xfs/ (default)
-m /usr/src/linux/System.map (default)

Error (regular_file): read_system_map stat /usr/src/linux/System.map failed
