We are going to release a new kernel soon, right now it is in the proposed channel, Welcome to test with the new kernel:
edit the $rpi_rootfs/etc/apt/sources.list and add: deb http://ports.ubuntu.com/ubuntu-ports eoan-proposed main restricted deb http://ports.ubuntu.com/ubuntu-ports eoan-proposed universe deb http://ports.ubuntu.com/ubuntu-ports eoan-proposed multiverse boot the rpi board, then run: sudo apt-get update sudo apt install linux-image-5.3.0-1013-raspi2 sudo reboot Then you could do the test with the proposed kernel.
