I ran it on my 64-bit machine and it hung because the interval was so short that it generated a continuous stream of signals. Each signal took longer to process than the interval of the timer. I added some memset's (since stack variables are uninitialized, and stuff like sact will get some random values in it if you don't). I changed the interval of the timer to be 1000 usec, and changed LOOP_LIMIT to be 1E6, and I got the catcher to be called multiple times. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
