Hi monochrome, back to keyboard, it tried newest CURRENT (r365920) on my box and even with newest sources the error occurs. After looking around somewhat more, I found some hints about Virtualbox kernel module having problems with r365488. Unfortunately, I am not able to find the thread again :( What seems to help as a workaround is to disable the loading of VirtualBox in /boot/loader.conf #vboxdrv_load="YES" and in /etc/rc.conf #vboxnet_enable="YES" #vboxguest_enable="YES" So probably, this page fault is not restricted to AMD Ryzen?
