Hmmmm, getting close but not yet a winner :-) 

I've been tracking the 2.6.29 rcx series and I'm still having some
problems. 2.6.29-rt1 still does not shutdown correctly with my kernel
configuration options (you need to specify "noreplace-smp" in the kernel
startup line for shutdown to happen - otherwise you get a problem at the
very end of the halt and the machine does not power down). 

And I have seen it hung (hard) the whole machine where a normal kernel
would just work. I'm still trying to find a way to debug that.
