Hello all,
I do not wish to repeat myself as I have addressed this issue in a recent thread, but this is too important to turn a blind eye to as even lives could be at stake which certainly makes it worth a separate thread: I believe I managed to conceive a program that causes a failure of RTX on a LPC2468/2478 (simulator does not induce the failure). Quite some people have reported problems with RTX on this forum, so hopefully they can download my stripped test program here dl.getdropbox.com/.../LPC2468_RTX_Demo_min.zip to try there own variants. I have of course informed Keil support about this issue and I am currently waiting for feedback. I would very much appreciate any feedback you might have.

"However the number of cycles varies between interrupt controller implementations and I haven't seen any documentation about this." Neither have I. And it isn't easy to guestimate the required number either. Some thing that seems to work after extensive testing can still be one clock off, just waiting for that other interrupt to come and catch you with the pants down :(
