Since I've upgraded from Fedora 21 to 22, my system sometimes suspends without any reason, even when active. I suspect the issue might come from the Intel graphics driver because of this excerpt of the system log, obtained with drm.debug=14 (see full log attached):

This is with kernel 4.0.6 and xorg-x11-drv-intel 2.99.917-12.20150615.fc22. No external monitor was plugged at any point. I have set acpi_backlight=vendor -- if that makes any difference I can try without.

My card is an Ironlake Mobile:

It's a systemd bug.
