I hope I'm not way off base (Having only one machine...;) but I understand
ftp://ftp.gcom.com/pub/linux/src/gdbstub/gdbstub-2.0.24.tar.gz (For 2.0.24
kernels, but not difficult to adapt...) does just that. There's also
gdbstub-2.0.24-10dec96.tar.gz version, altough I'm not sure what (if any)
are the changes. Author is David Grothe, dave@gcom.com: "I have GDB
running between two Linux boxes with a serial interface cable between
them. I can set breakpoints, single step and do source level debugging in
the kernel from one machine to the other."
