Do you mean the second channel on-board, or one of the serial ports that
are available using the IPMC-761?
I set console=ttyS1, and the result was similar to what you saw, the
board locked up.  I don't recall if I let it reboot (ie was it a panic or
a lock-up.)
I also tried just echoing some text to ttyS1 and it locked up as well.

I also tried using the ports available on the IPMC and got no where.
They don't seem to be recognized, unless I left out some kernel option.
I'm using the 2.4.23 kernel from the linuxppc_2_4_devel tree.

Please let me know if you find a solution to this.
