I'll bet you are trying to use /dev/reload to start the new kernel.
That will NOT WORK if the kernel_reload() procedure in locore.s is not
at the same address in the new kernel as it is in the running kernel.
Changing LEV6_DEFER changes the code in locore.s, and kernel_reload()
will change position. The latest big changes in -current for the Amiga
had a change in locore.s that will also change the location of
kernel_reload(). You HAVE to boot the new kernel from AmigaDOS in this
case. [Once the new kernel has been booted from AmigaDOS, you can use
the /dev/reload - until the kernel_reload() procedure changes location
