Thanks for the bug report. Do you prefer to continue the discussion here, on gitlab or on bugzilla?
## Reproducing
- Boot system to framebuffer console.
- Run `systemctl suspend`. If undocked without secondary display,
suspend fails. If docked with secondary display, suspend succeeds. 3. Resume from suspend if applicable. 4. System is now in a broken state.
So I guess we need to put those devices to ACPI D3 for suspend. Let's discuss this on your preferred platform.
