Public bug reported: Description is almost the same as https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1807534
Ubuntu 18.04.5 LTS, all packages up to date gnome-shell 3.28.4-0ubuntu18.04.3 Sometimes gnome-shell freezes. I can move the mouse pointer, but the rest of the UI is completely frozen and does not react to mouse clicks or keystrokes. If I try to change login session with Ctrl-Alt-F1, I can login but the screen remains black. I generally manage to "unfreeze" gnome-shell by switching to a virtual console and typing "killall -3 gnome-shell" dmesg shows a page allocation failure in gnome-shell, cf attached file.
