I was referring to the linux kernel itself - you can get fully patched
sets from somewhere, I believe, rather than having to hand patch and then
recompile the linux kernel.

Well, correct compilation just means that the program was syntactically
correct, and all the necessary files were available, there's no guarantee
that the program will work!!

I have to say, I don't like the idea of RTLinux on 2.2.*. I'm not wholly
enamoured with the idea of running a full linux kernel over a real time
system either, but I suppose with the limited POSIX real time support
linux has, it's the only way to do it currently. I presume you're using
RTLinux to access some hardware device or something? To be honest, there's
no real reason why you need 2.2, I'd stick to 2.0. It's rock solid ;)

Cheers,

Alex.
