I've noticed similar events on my system. In my case, I'm not using any
interrupts. I suspect that the periodic task runs with a period of 0
while the module continues to load and finally define the correct
period. I'm guessing; I think I have some timestamps to support my
conjecture. Eventually, the module runs the RT-task correctly but for a
while, the keyboard and mouse are locked. Any clues? I can't reliably
reproduce this yet.
