Automatic suspension causes the system to freeze on resume. This doesn't happen if I suspend it manually by opening the system menu and pressing the suspend button. Suspension works flawlessly when it is triggered manually.

When the system resumes from automatic suspension, the lock screen is visible but does not respond. It's frozen. A notification says "system will suspend shortly due to inactivity". It never goes away.

The keyboard responds during this (at least for a while). The CAPS LOCK LED turns on and off as I press it (with no delay). Sometimes I can even switch to another TTY and kill the X server, which is why I'm reporting it against gnome-shell. When switching TTY is impossible, I use the "REISUB" combination to shut down. Either way, I always lose the running session.

This is reproducible about 60% of the time. Eventually I ended up disabling it and relying only on manual suspension.
