Re: Problem with starting up 2.4.21 kernel

 There are mainly two things that you sould check:

1. Have you configured correctly the timers? It
depends
from your configuration, but ppcboot could pass to the
kernel the clocks in Mhz, although kernel could need
it in Hertz.(I dont remember exactly who needs what,
but I hope you understand that the mapping sould
be the same..)(Well, I always had to change that
inside the kernel..??...)

2. Have you correctly configured the serial interface
(where you have your console)? SCC,SMC..etc.

And, could you see inside the System.map in what
function does your kernel locks?

After "Transferring control to Linux (at address

BDI2000 I discovered that it shorlty after locks at
0xc0092aec address (the MPC866ADS eval board used).
I tried to turn on the kernel hacking options and
turn off everything I don't need right now but it
does not help a lot.
Could anybody give me a clue what this could be
about.

Thank you in advance for any help.
