Comment 6 for bug 1997178

Upgraded to a Nvidia RTX 4090, and initially sleep seemed to work for a few weeks. After the last few kernel updates, sleep again is frequently (but not always) failing to wake, sometimes resulting in a hang at a black screen (responsive to Alt+Print+REISUB), sometimes in a automatic reboot after a couple minutes.

Attaching excerpt from systemd which covers the sleep, though it does not seem to record anything related to attempted wake before the force reboot. Oddly systemd is treating it as a single boot even though the system force rebooted.
