I tried latency -t 1 on an SMP machines, and observed a very reproducible crash. Most of the time, the machine locks up completely. The rest of the time, I get :
Xenomai: suspending kernel thread e7559044 ('timerbench') at 0xb01051f2 after ex ception #14 And the system remains runnable, but 0xb01051f2 is not a valid kernel module text address. The lock up does not seem to be detected by any Xenomai or Linux debug or watchdog. Only enabling the NMI watchdog seems to systematically produce the exception 14 instead of the lockup. I ve tried to put a printk at the beginning of timer_task_proc outer loop. It get printed once when getting the exception 14, and twice when getting the lock up. Any idea where to look ? -- Gilles Chanteperdrix. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
