powerd on 8.0, is it considered safe?

OK, a reboot somehow fixed the powerd issue:

1) Disabled powerd
2) Rebooted
3) Upon bootup, checked dev.cpu.0.freq - it's stuck at 1249 (should be
1666 by default)
4) Enabled and started powerd - CPU scales correctly according to load

There is some bug somewhere though, because something puts my CPU to
1249 Mhz upon boot with powerd disabled and it gets stuck there, this
shouldn't happen.
