   I guess I could use a little more info before I even suggest a path
for you to take. when you say the "Ubuntu rt kernel" is this just the
standard rt kernel but supplied by Ubuntu, or is this an Ubuntu kernel
(i.e. - a kernel.org kernel patched with Ubuntu patches) and then
further patched with the rt stuff?

   My #1 suggestion is to make sure you are just using the standard rt
kernel. I had a bit of trouble with 2.6.25-rt so I stayed with 2.6.24
for a while and just recently moved to which is working
fine for me but did require that I reconfigure it from scratch instead
of using make oldconfig so building it was a little more painful. It's
working well though.

   I guess it's just me but I don't understand the motivation for
running the newest rt kernel. I upgrade every 2-3 major kernel
revisions these days, or when I hear about a major bug, security
issue, etc. I used 2.6.21, 24 and now 26.
