What is the cause for kernel: cmd ntpd pid # tried to use non-present sched_setscheduler?
Depending on your options for kernel configuration, the required functions may not be included in your kernel. Unfortunately autoconf seems unable to detect it. Check if these options are included in your kernel config file: options P1003_1B options _KPOSIX_PRIORITY_SCHEDULING options _KPOSIX_VERSION=199309L Make sure you have done config ; make depend ; make ; make install ; reboot.
