We have a board, similar to the SabreLite.

If the kernel configuration with powersave governor and USB support (ECHI 2.0 hub) then board is loaded, but does not work at temperatures below 5 degrees Celsius.

If the kernel configuration with performance governor and USB support (ECHI 2.0 hub) then board is not loaded. loading stops after initialization DVFS and before or during the initialization of USB and then nothing happens with the board.

If the kernel configuration with performance governor and without USB support (ECHI 2.0 hub) then board is loaded and stably operates at a temperature below -30 degrees Celsius, but does not work USB bus. we need a USB bus.
