I am referring to the ICTRL register of the MPC823.  It is set in
mpc8xx/start.S .
This was my mistake, I had modified the value while getting ppcboot to work
on our board and forgot to change it back.  The value should be 7.  I had
set it to 3, which according to the manual means:  "Core is fully
serialized
and no show cycles will be performed for fetched instructions".
