Actually, it turns out straight 2.6.15-rc1 is unstable under -skas0 mode on my
intel laptop. It boots up and gives me a shell prompt (which is all I tested
the first time), but if I type whoami (my standard "is this a UML or a host
system prompt" test), it panics with:
sh-3.00# whoami

What do you want dumps of? (Keep in mind this is straight -rc1. As of
yesterday I can't get your current patch set to even _build_ on my 32-bit x86
ubuntu laptop.)
Let me know what you want me to try...
