Q. 1, did you edit the toplevel Makefile, and edit EXTRAVERSION to =
  "-itv"? If not, it will be looking at the wrong files.

Q. 2, have you also copied the System.map to
/boot/System.map-2.4.18-itv?

Also, perhaps the image is too large for the ramdisk. At least
temporarily, try this on the config for that kernel:
  append="ramdisk_size=10000"

(about 10 MB)

I think if it is too large for a ramdisk it does something similar to
wrapping around putting garbage instructions in, which in turn might
cause a triple exception in the kernel (forcing instant reboot). The
above is all speculation, but easy to test.
