Hello... > Why is registering an empty function and calling it from inside do_timer > freezing the system after a short period of good run? There are several suspects: 1. your code (call_timer_hook) is called while xtime_lock is held. it could lead to lock contention. 2. you're running out of kernel stack. I don't have hard proof, purely blind guessing. Try to make all your hook function a "static inline" one. Silently overflowing kernel stack, AFAIK, is hard to detect. Do you use 4K or 8K stack size? try 8K and see if it helps. Before I forgot, you said it runs OK for after (quick?) period? So this problem is intermitent? regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
