Soft lockup when monitors are in power saving mode

Every couple of days, when I try to wake my monitors up, they will remain asleep and completely unresponsive to keyboard and mouse input. Similarly, switching to a virtual console also doesn’t work.

I wish I could provide reliable steps to reproduce the issue, but I can’t. It seems to happen entirely at random. The best steps I can give are: Allow the monitors to go to sleep. Come back hours later and try to wake them up. There doesn’t appear to be any rhyme nor reason to what triggers a lockup.

I’ve tried grabbing an nvidia-bug-report, but in the rare instances where I can SSH in, anything I try to do will give me a resource temporarily unavailable message.

The only recourse when this happens is to hard reboot the machine.

I’ve heard some rumblings that this might be due to poor UEFI implementations, so I tried in a “legacy” install and the same issue occurs.

Driver: 381.22
GNOME Shell 3.22.3
Fedora 25

Monitors: Two Dell P2415Q’s connected by DisplayPort
Video Card: Gigabyte GTX 970 G1
Motherboard: GA-Z97X-Gaming GT (F7 BIOS) (Currently in ‘legacy’ mode, but also happens in UEFI)

The log file is inundated with messages similar to these:

I have seen the same issue today. @filchermcurr have you found a solution to fix it?
