I have a test program which made a loop in RT to mesure the system
perturbation.
It works finely in a tty environment.
When I run it in an X environment ( xterm ), I get something like if I
click the Enter key in the active window.
If I open a new xterm, this is the new active window which receive these
events.
These events stop when the program stop.
I tried with X in RT and no RT : I have the problem.
I send you the program in copy to reproduce.
I have this problem in all version of RT.

Try adding:
Option "NoAccel"
to the Driver section of your X config.
Some buggy video drivers can stall the PCI bus for tens or hundreds of
*milliseconds*. The "via" driver had this problem until I identified
the problem and the Unichrome guys fixed it. If it goes away with
"NoAccel", then you are having the same problem.
For details search the unichrome-devel archives for "losing interrupts".
