#17664 fixed Crash in hdaR3Timer, Fedora 27 host, Oracle Linux 7.2 guest -> fixed in 5.2.22 Max Fedotov
Description

VirtualBox crashes when any gnome based application is started, including gdm and gnome desktop, but only with guest additions installed (3d acceleration disabled). With 3d acceleration enabled I get kernel panics and oopses, system can not load. Worked fine in 5.2.6. Guest kernel is 3.8.13-98.7.1.el7uek.x86_64

Host system - Fedora 27 x86_64

#17663 fixed Graphics lockup leading to VM lockup with Fedora 27 guest -> reported fixed in 5.2.10 Kevin L Mitchell
Description

On a Mac host, I have a Fedora 27 guest using the Cinnamon window manager, which requires 3D acceleration. X server version is 1.19.6. With the VBox 5.2.8 release (and at least with 5.2.6 prior to that), I've been experiencing a problem with graphics lockups that, if not addressed, leads eventually to a full guest lockup. This is a frustrating problem, because I haven't found any logs with useful information on the guest side, and only just discovered the logs for VBox (which I'll attach). (For the record, I am using the guest additions provided with VBox, rather than the guest additions available in the Fedora package repositories.)

The main symptom of the problem is that graphics stop updating: the clock running in the X desktop stops updating, and the only graphical element that functions is the cursor. I also hear the host fan spool up, so whatever is happening is causing a high CPU load. If I catch the problem right away, I can switch to a text terminal and kill the Cinnamon session; this causes X to restart, and seems to clear the problem. If I don't catch the problem, however, eventually the guest completely locks up and has to be hard reset.

As for the cause of the problem: anything that produces high graphics load does seem to increase the likelihood of it appearing; for instance, I just experienced a lockup while attempting to watch a video. However, graphics load is not the sole cause, as I was able to watch that video and much more after the X restart (without restarting the VM). Additionally, the lockup has occurred with the system completely idle; I had this condition occur over the weekend, where I came into my office on a Sunday evening (computer had been idle since Friday), and heard the fan and was able to intervene and restart X. The problem occurs regularly enough that I have had to restart X twice while showing a presentation to some coworkers, yet can have a period of up to a couple of days with no problems.

I will be attaching two files: one from the last time I had to hard reset the guest, and one from the current session, where I've had to restart the X server by killing cinnamon-session.
