Hi, I was able to formulate this command, echo -1 > /proc/sys/kernel/sched_rt_runtime_us chrt -f 99 yes &> /dev/null and it works sometimes on UP, but it doesn't work on SMP. I also tried adding in "taskset" to pin multiple version of the "yes" command to each cpu in the system, but that just resulted in lots of rcu warnings. The goal is to make the watchdog trigger by starving out the watchdog petting process. Anyone have any ideas? I'd rather not make a kernel module. Thanks, Daniel
