[U-Boot-Users] debug linux kernel hangs

Thanks your help. Just because the serial console can not work on my
board, so I step into kernel to trace.
I think maybe the kernel init sequence can not arrive the console_init(), so
I can not get any message after run "bootm". It just told me "Uncompressing
Kernel Image ... OK", then it hangs.
Bye the way, I only the u-boot 1.1.1 and linux kernel 2.4.22 in hand, where
I can find the lastest code?
