Works for you on this exact Supermicro?

I am using the defaults all around.  This is booting BIOS mode PXE, all
console output appears on the IPMI SOL interface.  Driving the beastie
menu in pxeboot/loader works fine.  When the loader hands the uart off
to the kernel, I see all boot output and "everything is fine"

The problem arises when trying to login.  I see the amnesiac login
prompt, but no key strokes are registered.

loader.conf:
console="comconsole"
comconsole_speed="115200"

boot.config:
<does not exist>
