Cannot resume from suspend with AMD gpu enabled

I had my AMD gpu (radeon r7 m365x) disabled in my BIOS settings on my laptop (HP EliteBook 850 G3) . Today, I enabled it back and it seemed to work fine until I try to resume after suspending the laptop.
This gives me a screen with the following error message instead of showing the login screen (using Xfce with LightDM).

mei_wdt mei::05b79a6f-4628-4d7f-899d-a91514cb32ab:02: Could not reg notif event ret=-22

When I try to switch to another tty, it quickly flickers the login prompt and then shows the previous error message again. I also cannot type anything.
I did not have this problem when the amd gpu was disabled in the BIOS settings.

Edit: I solved the issue by using a different screen lock program (slock instead of light-locker). The issue was caused by locking the screen with light-locker, not by suspending. However, I would still like to know how to solve this with light-locker.
