I agree with Ron. JTAG debuggers are more robust. But I am interested in stepping through LinuxBIOS on a working target to quickly understand the code, so I'm able to attempt a port to a new target. I view it as a learning tool and a productivity tool. If you could show people how to use a product like the American Arium, you might get more help.

using a remote debugger that way. What a jtag interface provides is really not much more than what gdb stubs provides. At least not after memory is initialized.
that's not quite correct. There are a host of cpu failures you can detect with a jtag interface that gdb stubs are useless for. GDB stubs requires
that the processor be basically sane, jtag interfaces are not near as picky.
