The same problem is that the kernel doesn't survive until the welcome
messge is printed.
The kernel is loaded with ppcboot and the tftpboot commando. To trace, I
used mpc8bug.

I use the Montavista linux-2.4.0-test2-1.2.0-1 kernel.
I set a breakpoint at the entry of the __start routine. After passing
the turn_on_mmu label, it returns with an rfi and hangs.
It is maybe ment to be started from a power_on interrupt, because in
this context, I don't see the sense for an rfi. But I don't know much details.


I believe there is a working FADS port in the FSM Labs BitKeeper

The Montavista is the one I used. I also tried one from Bitkeeper, but I
didn't found support
for the FADS board. Even when I compiled for MBX, I got no image in
arch/ppc/coffboot.
Which is the machine type I should configure for a MPC860FADS?

It would be nice if you could help me. So far I couldn't start any kernel.
