I assume there is an IPMI kernel driver / codec involved in the serial
traffic on the kernel running on the remote device. It is entirely
possible that you will not be able to make this work easily. KGDB
relies upon the fact that you can have some type of I/O driver which can
be used from the exception context where the interrupts are off and you
touch as few pieces of the kernel as possible.
I have not looked at how the IPMI serial drivers work, but I suspect
they rely on interrupts being on, in order to function, in which case
you would need implement some kind of explicit polling support.
