@Kai-Feng. The other bug regarding p-state as disappeared (I cannot access it on Ubuntu bugs). This bug also appears to be fixed as p-state is now the default scaling driver. However tlp stat is showing unusual max/min cpufreq settings after kernel installation. Do these settings seem incorrect and/or are they even used by the pstate driver?
