I did notice a problem with the internal timers and reported it to the
rt kernel gang, the effect was repeated keys when typing and problems
with the screensaver. I'm sure that is the reason for the (probably
false) xrun messages. 

You should try the rt23.2 build (on fc10, still have to build it for
fc11) which reverts part of the timer changes between rt22 and rt23
(Thomas Gleixner sent me the patch), the kernel seems to work fine after
