--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
This is not a bug, drivers/cpufreq/intel_pstate.c is loudly reporting that it
has no "turbo" (marginal overclock) frequencies. It is not even igt that is
writing to /sys/devices/system/cpu/intel_pstate/no_turbo that triggers the
warning. Look carefully at your own system; and file a bug against intel_pstate
if you find the warning obnoxious, after all it is triggered by userspace and
an error is reported already.
