Hi all,
I'm working with a ppc board that uses mpc8548e processor. This board has
1GB of ram. I have configured the uboot, but when I run the kernel (linux
kernel 2-6-10 from montavista software) with the initrd I have a kernel
stack overflow error. We locate the error in the "unpack_rootfs" kernel
function when it is read from initrd_start passed by u-boot.
we attach the serial output including the loading u-boot.
