[parisc-linux] Many experiments on 720, but `init' fails !!

This could be a simial problem, but in your case, another problem
is also likely.
You have a 9000/730, which really has *one* CPU. (There a three
chips, AFAIK, one is the CPU, one is a FPU coprocessor, and the
third often has to do with the cache). 
The only difference is the CPU core speed (66HMz 730, 50Mhz 720),
and perhaps the machines are equipped a little different.

"Our" CPUs are very old. So there must be a line added in 
the arch/parisc/kernel/trap.c file. In the handle_interruption()
you must add the line
	`case 18:'
where
	`case 15:'
	`case 26:'
is in the code, because these old CPUs use an older method of
"reporting" page faults, etc...

But as you have the output of the "break" routine, this seems
not to be the interrupt code.

In my case it is pid=9. I have not find out yet, which "kernel
thread" pid will get.

With friendly regards
