If you force vboxvideo to build by editing the makefile, you get a file that crashes when you try to use it. Going back to 5.1.x works fine however.
There error given is: kernel: [ 17.290464] [drm:vbox_bo_unpin [vboxvideo]] *ERROR* unpin bad ffff8f5597836400 So somehow the 5.2.0 version is just plain broken it seems. -- Len Sorensen
