I get the same freezes
 with CONFIG_MCORE2=y       CONFIG_X86_GENERIC=n
 and  CONFIG_M586=y         CONFIG_X86_GENERIC=y
 and  CONFIG_MPENTIUMIII=y  CONFIG_X86_GENERIC=y (-krgn)

You guys are way ahead!  I was going to suggest cherry-picking
git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-linux.git
Which exhibits the same problem.

Collecting patches probably yields a distributable binary in shorter time.

I'll look into DNS for git.linuxaudio.org and we should discuss
collaborative work-flow in a different thread.

just brainstorming: would sth along the lines of
http://fate.multimedia.cx/ be feasible for rt-linux? - well, the
"tests-passed" is obviously crazy to implement. But a "per compiler"
"per ARCH" public stderr is definitely nifty. and I'd be surprised if
there is no such system yet ;) - it's hard to keep track these days..
While I do know my way around, I'm not a kernel hacker.
