Thanks for the lively discussion and input. It's now clear to me that I'll be tracking (not tracing) the kernel with the h/w debugger through its kgdb shell. We're still working on some drivers, so control over the kernel is a must. I'll have to set up the server to autoload when a connection on a particular port is attempted from another gdb shell, and shut down on disconnection.
