This is related to your BIOS or motherboard. Do you have the same
problem with a vanilla 2.6.29?
Since I only did reboots, I just performed a shutdown to check and it
powers off just fine. I don't use any boot options (only "root=xx quiet
ro") on this dual-core intel.
Why shut-down, anyway? s2ram and s2disk work fine with 2.6.29-rt1. I'm
very very happy (-:

I did not have those for a long time (~2years), previously I experienced
hard lockups when using wifi (iwl3945) and rtirq.
I dare say there's no way to debug that - but you should ask that on
rt-linux list. There's ways to tweak things in /proc/sys/kernel/sched_*
if this lock-up is caused by a runaway process.
It could also be CPU overheating, but then the problem should also occur
with non realtime kernels as well.
