I will copy and paste my summary below. Updates since I created that bug: * This occurs with the mainline PPA 4.18.12-041812-generic kernel. * The glxinfo section I include below is identical with 4.18.0-11-generic (presumably no surprise). * I would appreciate a bit of hand-holding for bisecting this. Does the kernel team have ready-built kernel packages for bisecting? Or guidance about the fastest way of doing it (i.e. not rebuilding things which do not need to be rebuilt for successive rounds)? === Original report follows === When I start a VirtualBox virtual machine (reproducible with the Ubuntu 18.04/VirtualBox 5.2.22 packages from virtualbox.org) with VMSVGA emulation and 3D pass-through enabled, my system hangs. Sometimes I can recover if I get to a VT fast enough to kill the process. Also, the OOM killer sometimes triggers and kills the process or gnome-shell, but the OOM killer entries in dmesg look like neither of the two are using excessive memory compared to available system RAM. When I switch to the Ubuntu drm-tip kernel packages from the kernel PPA the problem goes away. Debugging shows that the hang occurs during the first glXMakeCurrent call made by the application. It did not occur using the standard Ubuntu kernel but running the application under apitrace. I can provide the trace if that helps.
