Early kernel debugging

[Guillaume Dargaud]

Hello all,
what can you do when the kernel you try to run stops before printing anything on the console ?

I tried enabling the 'early printk' option, but still I get nothing.

I posted something about it in the 'Booting with ramdisk in kernel' message and I haven't improved the situation since 
then, although I found the CONFIG_BLK_DEV_RAM option.
