Hi Tomasz,

After UP2 boot up with native, Could you please try following command with uart disabled first?

sudo efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/mmcblk0-p 1 -L "ACRN Hypervisor UP2" -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi uart=disabled "

This means you boot sos kernel directly without ACRN.
That I figured out already yes.
But why? (installer did not show any issue, the only thing which seems
suspicious is the EFI bootorder as I described)
And how to fix this?

Not sure whether you are familiar with EFI shell. If yes, can you

try to load acrn.efi from EFI shell? That make sure the ACRN is
