yes, I guess your prolbem is like what Christian said before. Tye using
console=ttyS0,9600 to append boot options.

Thanks for the suggestions, guys.

Actually, I had the statement above in my default command line option
compiled into the kernel. I also tried adding it to the "bootargs"
environment variable in U-Boot.

The exact same kernel boots with the IBM bootloader, including serial
console and network access. When I boot using U-Boot, I don't get a console
and there's no apparent network activity from the board.

How about the log_buf contents?

And did you try attaching a debugger?
