The last few statements are: There are known problems with CPUfreq on top of the new clock notifiers series. I am waiting for Rajendra to re-send his series which removes the virt clocks on top of the latest PM branch. > <3>clock: dpll5_ck failed transition to 'locked' > clock: dpll5_ck failed transition to 'locked' > <6>Disabling unused clock "dpll4_m6x2_ck" > Disabling unused clock "dpll4_m6x2_ck" > <6>Disabling unused clock "dpll3_m3x2_ck" > Disabling unused clock "dpll3_m3x2_ck" > <6>Disabling unused clock "sys_clkout1" > Disabling unused clock "sys_clkout1" > > The PC is at the WFI statement. > > Tried other combinations as well: > > 1) only CPUidle enabled - okay. > 2) only CPUfreq enabled - not okay. > Sounds to me like CPUfreq is changing frequencies during bootup. Did you select ondemand as the default CPUfreq governor? If so, can you try with performance as the default governor. If you're already using performance, then u-boot is setting a slower speed and CPUfreq may decide to change it during boot. If so, can you try the userspace governor as the default governor. This should prevent any automatic CPUFreq changes during bootup.
