Hi, Can you give the latest mainline kernel a try to see if this issue exists in the upstream? https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.13-rc7/
Please download and install amd64/build generic deb files (files marked A, see section "How do I install an upstream kernel?" in https://wiki.ubuntu.com/Kernel/MainlineBuilds) and reboot, let us know if it works and paste your "uname -a" command output in a terminal (ctrl+alt+t) here.
