Have done this.

$ apt-add-repository -p proposed
$ apt install linux-raspi

Switch from fkms to kms

$ reboot

uname -a
Linux RW-RPI2 5.13.0-1008-raspi #9-Ubuntu SMP PREEMPT Wed Sep 29 08:27:44 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux

Test with kms. Result: video and system freeze after ca. 6sec video-playing. So i return to fkms.

$ sudo dmesg | grep -P 'firmware|WARN'
[ 0.116401] raspberrypi-firmware soc:firmware: Attached to firmware from 2021-02-25T12:10:40, variant start

With kms video freeze, mouse cursor freeze, system freeze. With fkms no issue. Sorry, but this don´t helps.
