Just made an successful ncp-dist-upgrade to Bullseye on NCP v1.47.2 on Rock64 board. Thanks to all the developers. 
Then I upgraded kernel from legacy(4.4) to current (5.15.35-rockchip64) and that broke booting from USB3-SSD 
Error
Begin: Running /scripts/local-block … done.
Begin: Running /scripts/local-block … done.
Gave up waiting for root file system device …
ALERT uuid=… does not exist. Dropping to a shell!
Booting from USB2-attached SSD still works. Plugging device in USB3 after boot also works… Looks like a bug in armbian/kernel/bootloader(?) described here
Be prepared, Rock64 owners.
