Public bug reported:
I configured CPU0 and CPU1 to use ONDEMAND.
htop shows me that CPU0 and CPU1 have both around 3% usage (while being
idle in gnome), but still
- CPU0 always stays at 100% (2.13Ghz)
- CPU1 stays at 37% (800Mhz)
- If the CPU1 usage goes over 5%, it is shortly boosted to 100% (2.13Ghz)
