Same symptoms, but needs more stressing of CPUs to exhibit the kernel crash. This instability ALSO exhibits itself on a MacMini (Apple) Mid 2013 with 4 core.also with VMware Fusion 7.1.2. However, the impact can be devastating for those whom try to utilize VirtualBox for some type of production level system. That's because after 10 crashes, and inspecting the OsX System Logs, there are common messages produced in that log, which would give clue to the fact that VirtualBox had any problem, OR that any other OsX driver or subsystem had any problem. Thus you have a very insiduous problem going on within your KEXTs for OsX. It is important to note, that VirtualBox is causing OsX kernel instabilities, even when no virtual machines are running on the system. There have been no more kernel instabilities since the complete VirtualBox removal. The complete system lockups, where 2 of the 3 monitors would immediately go black, leaving desktop still showing on a 3rd monitor, on a 2nd GTX-980, were traced to VirtualBox as the culprit, by using your Un-Installer to remove VirtualBox and it's KEXT(s) from the system.

It was after the VirtualBox installation that the kernel instabilities were introduced. I installed VirtualBox 5.0.16 on the OsX-Yosemite 10.10.5 system, (which, BTW, did also have Fusion 7.1.2 installed on it). Unfortunately, I'm in midst of critical timeline of another SW dev project, but thought I would report this problem anyway. It's possible that your developers are already aware of this crash.
