Thanks for the encouraging feedback. It is good to know that things are
working out. I would not imagine that at this point we would get much
better latency performance from these kernels (I'd of course love to be
proven wrong) unless I change the configuration options that I'm using
when I build them (from PREEMPT_DESKTOP to PREEMPT_RT). I have not done
any tests with PREEMPT_RT in a long time, maybe it is time to fire one
up and see what happens...

I'll send this to Ingo, I'm sure he'll be happy to know of satisfied

And, of course, once you install one you have another :-)

2.6.12-0.21.rdt is out now in the PlanetEdge repository (including
realtime preempt 0.7.51-27), with some fixes that Ingo believes will
prevent some lock-up conditions. Probably not worth upgrading right away
unless your machine locks up sometimes :-)
