I work on a custom board based on MPC8xx.
The bootloader on it is a ppcboot 1.1.5. I'm a beginner with Linux port
and ppc.
I'm trying to pass the board working with a 2.4.4 kernel to a 2.6.19 kernel
from denx.
The kernel hang when trying to enable interrupt in local_irq_enable()
in init/main.c.
Nothing happened after. Look at the printk log dumped from __log_buf
adresse with md ppcboot command.
