Description Ang 2020-11-30 21:13:47 UTC 
I am currently running Tumbleweed aarch64 20201119 on a Raspberry Pi 4 off a USB flash drive with no SD card installed.
Tumbleweed was installed using the ISO written to a USB 3.0 flash drive. The system is running the latest stable EEPROM firmware (updated using Raspberry Pi OS 64-bit).

The system was booted directly off the Tumbleweed installation ISO on the USB 3.0 flash drive with no SD card installed. It was then installed on another USB 3.0 flash drive installed in the lower USB 3.0 port with the following software selection: XFCE Desktop. After the system was installed, it booted straight off the USB 3.0 flash drive (no need to use gdisk as with the Raspberry Pi 3).

When using the system, I constantly get the following messages from dmesg when no SD card is installed (3 different commands, 0x00000502, 0x0000371a, and 0x0000341a)

Even with these messages, the system works as would be expected.
Comment 1 Nicolas Patricio Saenz Julienne 2020-12-01 10:37:47 UTC 
This is being worked on at the moment, a temporary solution is to add `dtparam=sd_poll_once` to /boot/efi/config.txt.
