Hi,
   Sorry. I didn't read this thread due to the title but when my nam
pops up I figure I'd better find out what people are saying about me.

   I'm writing back on my AMD_64 here. It's certainly stable and
doesn't crash. I can forward a 2.6.15-rt18 .config file to someone.
(Carmen? email address please. Florian? Drop me a note if you want a
copy.)

   One note: Based on a comment Lee Revel made a few days ago, I think
on this list, about the standard kernel giving good realtime results I
built 2.6.16-gentoo-r2 on Saturday. It's now up two days with no
problems. I'm running at 128/2, and even 64/2 as shown below) in Jack
with no xruns so far although I've got a cold and am using it very
lightly right now. Anyway, I agree with Lee (so far!) that even the
current 2.6.16 series is giving much better performance than older
kernels even without Ingo's patches. IF it matters I use the
realtime-lsm module and not the othe PAM based stuff.
