Hello all, I've just joined up with this list, so this is mainly an initial "ping" to see if I can post. I'm a newbie studying embedded linux on an Olimex SAM9-L9260 target, cross compiling on Ubuntu 8.10. Eventually I'd like to ask a couple of questions. On the subject of timer INTs, I actually just got timer callbacks going in this sort of newbie handler approach : static void timer_fire(unsigned long data) { mod_timer(&timer_ticktock, jiffies + (timer_tick*HZ)); printk ("Timer fired at %lu jiffies\n",jiffies); } All works perfect, but *very* occasionally upon unregistering (rmmod) the module I'll get a segmentation fault. I've tried with protecting the module exit code, but still seems to be a snag. I'll provide better detail when I post properly. I hope this post pings OK - this looks to be a great list.
