Wow, that's great news! Desktop Ryzen+Vega doesn't (not that I need suspend very much on desktop haha)

Since it's a Thinkpad, do the brightness keys work anyway? Does acpi_ibm work?

If you're on the packaged drm-kmod v4.16, it's amazing that Raven GPU works at all. You should try drm-v5.0 from git.


It even works when loaded this early? Interesting. Do you also not have the EFI framebuffer conflict? i.e. without disabling vt.syscons, everything just works reliably?
