Just a small update: I need the suspend/resume cycle to work, so I reverted back to 4.4.114. Now my system as the following drm-kmp packages installed, but I am not sure how to determine which one is actually used: drm-kmp-default-4.9.33_k4.4.126_48-13.3.x86_64 Fri Apr 20 09:10:03 2018 drm-kmp-default-4.9.33_k4.4.120_45-10.2.x86_64 Tue Apr 17 00:13:42 2018 drm-kmp-default-4.9.33_k4.4.120_45-13.2.x86_64 Sat Apr 7 18:09:49 2018 drm-kmp-default-4.9.33_k4.4.114_42-7.1.x86_64 Tue Mar 20 09:23:18 2018 drm-kmp-default-4.9.33_k4.4.79_4-5.2.x86_64 Sun Dec 10 17:07:52 2017
