Application code compiled for a P4 (using full P4 optimizations) usually
won't run on a P3, I suspect the same for kernels. I betcha you need to
do the install again on the P3. I also betcha if you did the P3 1st &
then moved that disk to the P4 it would work. Newer CPUs can usually run
older code, but not vice-versa. YMMV & all that :-).
