I tried to install the mainline kernel and to sign it according to https://www.digitalpeer.com/blog/install-custom-or-mainline-kernel-on- ubuntu, https://ubuntu.com/blog/how-to-sign-things-for-secure-boot, https://github.com/berglh/ubuntu-sb-kernel-signing.
It seemed to work, but when I boot it says the shim signature is not recognized, or something of the sort. I'll try some more, but perhaps someone can point me to relevant and up- to-date documentation?

Status in linux package in Ubuntu: Incomplete Bug description: When working normally, random freezes happen. Everything freezes, except the mouse cursor. I tried from keyboard to: switch to another window, start a terminal, run a command to restart gnome, enabled ctrl+alt+backspace and tried it to restart X windows, ctrl+alt+delete, switch to another session with ctrl+alt+F1-F9 - nothing works. If I'm listening to something, the sound goes on for a while; sometimes it stops by itself, other times it keeps going. The only way to recover that I've found is to stop the laptop from the power button. For a while I thought it was due to firefox; I installed the deb version and then switched to chrome - same behavior. It didn't happen when I was playing Hollow Knight in Steam, or when I've used the terminal and nothing else.
