Hi,
I am doing booting linux kernel 2.6.14.5 from kernel.org on a kind of
embedded ppc board, where the chip mpc8272 has been settled.
But after u-boot(1.1.4) finished booting itself and uncompressed the
uImage(2.6.14.5 based). the kernel can not boot
Successfully. It stop somewhere. the script is below:

Then I have tried to use BDI2000 to debug the kernel, It seems that the
kernel can passed on console_init function. But still no message came
out even printk(KERN_NOTICE); and printk(linux_banner);
