Thanks. Can You try the same for longhaul with "scale_voltage" 
module option set to "1"?

Weird bug, but can wait. Seems to be present in print_speed().

In this moment I don't know if it is unsuccessfull frequency 
transition or problem with hardware. Maybe bits in EBL_CR_POWERON 
registers are stuck. Can You benchmark (any program You like) 
how fast Your CPU is after reboot and before modprobing longhaul? 
And compare it with results after modprobing longhaul and setting 
governor to "powersave"?
