I'm attaching the requested logs. Near the end of this file you'll see the last action I performed, which was the CTRL+ALT+PRINT+REISUB combination to reboot. You'll also see that there is a long crash log related to AMDGPU.
Oh, and this time when it crashed I attempted to switch TTY, and then the screen changed to a display of trillions of tiny colorful artifacts, like a TV with bad reception. ** Attachment added: "Logs from a previous session that crashed" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1917674/+attachment/5475553/+files/prevboot.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917674 Title: Freeze when resuming from automatic suspension to RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1917674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
