After resuming from a suspend, the display for my desktop occasionally stays in power-save mode. I can ssh into the box, but neither mouse movement or keyboard activity brings the display to life. I don't believe it's a problem with those peripherals, as the NumLock LED responds to presses of the NumLock key.
I see the "[drm:drm_mode_getfb] *ERROR* invalid framebuffer id" message in /var/log/syslog.
