I don't quite know where to go from here...
I have gotten the 2.2.10 kernel from linuxppc.org a while ago. I did not have
problems compiling it at all. I did:
moved the kernel and the System.map to the /boot and rebooted.
I get through the quik loader. (Booting from OF) but the screen does not seem
to clear like it does normaly. And then the computer hangs.
So what I am left with is the boot prompt in OF something like:
What I can figure is the kernel hangs somewhere before start_kernel and up
to and including the console_init function call. Because with my kernel which
works I think these messages are the same and the screen blanks and then starts
with the boot process.
in file init/main.c:
asmlinkage void __init start_kernel(void)
I have been trying to figure out where this is called so that I can try and
figure out what is going wrong? I have no errors from the kernel. I have
searched all the arch, include/asm-ppc and other directories I can think of in
Along those lines...
Is it printk which prints the messages on the screen at bootup. PRIOR to the
init scripts. I don't even get the linux_banner before the machine locks up...
Or if I am totaly off-base here...
Where does the kernel code start executing?
Thanks in advance
