Mike, did you apply the patch *and* mpirun --mca rtc_freq_priority 0 ?
*both* are required (--mca rtc_freq_priority 0 is not enough without the patch) can you please confirm there is no /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor (pseudo) file on your system ? if this still does not work for you, then this might be a different issue i was unable to reproduce. in this case, could you run mpirun under gdb and send a gdb stack trace ?
