wake up from suspend with "battery" radeon_pm_state

OK, I know what you mean now, Scias.
A few tests here:
1. Setting to "balanced" state, waking up is fast and OK. 5/5 times.
2. Setting to "battery" state, waking up is fast, but with a white screen, the
GPU hung. Sometimes I can see and move the cursor, but any other operation
cannot be done, e.g. switching to a tty. 4/4 times. I have to shutdown by
force.
3. Sometimes when the system booted into X(KDE splash screen), the GPU hung,
have to shutdown by force, not very often.
4. Powered by AC or BAT, the state is always "balanced".

For the last test, I have a question here:
Should it switch from "balanced" to "battery" automatically when I unplug the
power cabble or just stay "balanced"?
