There's no "quiet" param. The default UEFI boot options are "verbose" as a default.

I can't see *any* output from Linux kernel. Also I tried settings up SOL serial console,
but I can't see any Linux messages there either. SOL stays empty/silent.

Is serial console supposed to work OK in the usual way, with UEFI boot? 

And again: Booting in legacy BIOS mode works OK, and the serial console works there aswell.
I have problems only in UEFI mode, where I can't get *any* output from Linux.
