Thanks for taking your time, but the problem is still there. I have now tried using nanosleep() and clock_nanosleep() but the result is the same. But when I set the timer in periodic mode my thread ran for over twelve hours before I interrupted it so it seems as if rtl_time sometimes fails to re-program the timer chip. Some more observations: When my task is frozen, everything else timer related is frozen too. 'date' returns the time when the task froze, 'sleep 1' blocks forever. If I leave the stopped task in memory and don't touch the system it will start again after some time, typically it seems to take about 30 min. The same task seems to run OK under the same kernel version, same RTLinux version and same compiler but on a P4 1.6GHz. Any more suggestions anyone?
