Full realtime preemption is not yet in mainline. They just merged:

So for a full preemptible DAW kernel you'll still need ingo's patch
applied.
btw i had the same experience with 2.6.12 and RT... horrible stability,
not faster in any way as vanilla+normal preemption. The best so far is
2.6.11.x + rt, 2.6.13-rc6 is quite stable here, but i use it w/o RT and
am back on Con Kolivas -ck2 with new improved SCHED_ISO and very pleased
with it so far. But for a production DAW i would use 2.6.11.x + ingo's
RT.

have i missed something? i've been applying patches to the 2.6.13
kernel:
is this not required anymore (makes me wonder what i actually did
when patching that kernel then ...) ?

More unsubstantiated comment, for which I
apologise:

The 2.6.13 idea was probably the most helpful. Applying the rt
patch was an idea given by Revel, though not for .13...but thanks
for yelling at me about it anyway. .13 comes with the RT patch
applied already so it isn't necissary to apply any patch to this
kernel....not that I don't know how. Try the latest RT preempt patch that works with
2.6.12. Or, why not
just use a prepackaged RT patched kernel like the Demudi one?
I would guess that Noah has already tried it. There is enough
traffic on the AGNULA-users list to suggest that none of the
prepackaged DeMuDi 2.6 RT kernels are actually stable, they seem to
work perfectly on some hardware and not on others (partic. low-spec
and 64bit machines).
