Screen didn't help.
Moreover , using different OS distributions show same similar behavior !!

You meant baud-rate ? 

On uefi side,  could you help me if there is some extra information passed to OS in path 
UiApp -> BootDevice, 

I could see , some of additional protocols are installed in above path, I am not sure if those are
used  by  OS or OS Loader (grub in my case)  somehow.
