I'm saying it _can_ happen that it's easier to replace the kernel.. I'm
not saying it's always the case. We're talking about debugging
situations in an embedded environment which don't always follow a normal
path.

So you don't like it, that's fair enough .. <thinks>I wonder what other
maintainers I can send this too</thinks> ;)

Can you be more specific about your objections .. The discussion over
the ttyS* thing is still happening. I'm waiting for Hyok to give a good

why that part would exist, which is what I'm discussing with Alan and
Mike.
