This is probably a long shot, but I had the same issue when I did the 
original x86 port. It turned out that I had not routed the UART 
interrupt signal correctly in U-Boot - I think the Linux kernel may have 
been waiting on some kind of interrupt from the UART (probably buffer 
empty) before it sent anything to it.
