USB keyboard and mouse cease working on screen lock

[unholyeyebrows]

Hi folks

I'm looking for some help regarding a frustrating problem I have currently with F27 on a desktop PC. In short, when my screen locks (manually or automatically) my USB mouse and keyboard cease responding once the screen has gone into power saving mode. The PC is still running, and the USB devices still appear to be powered (judging by their LEDs still being lit) but neither tapping the keyboard nor clicking the mouse buttons are able to bring the PC out of power-saving mode. The only option is to hit the reset button.

I can confirm this problem was not present in F26 when I last had it installed on this PC around 6 months ago. Since then I've been running SUSE Leap 42.3 which was also unaffected. My Thinkpad X220 also running F27 does not see this problem, so this is peculiar to my desktop PC.

I've searched online and speculatively tried various kernel options but none have worked. I'm keen to try to diagnose this via the system logs but am not sure where to start. Any ideas would be most welcome!

Some hardware details from my PC:
