Maybe you know something, that I don't know, and want to share it? :-)

Take a look at src/sys/ipkdb, which is part of the reason it is not
"Hard", I guess.

I found ipkdb a few days ago. I found out that it is dead too.
Do you think it should be revived and new drivers written for it?

One important question to ask is what the *goal* of kernel debugging over Ethernet is. There are virtualization solutions that can be used to debug a kernel without hangs and crashes.

Think of it as an alternative to serial console for debugging purposes.
At least that is the case I would want to have it for.

Of course, we are talking about replacing serial port debugging, as serial ports are becoming increasingly rare. I'm just interested in other ways of debugging the kernel and how remote kernel debugging over Ethernet will fit in the grand scheme of things.
