Comment 6 for bug 1580459

I think this is what's happening to me on my windows 8.1 vm although it might be slightly different.

Just about everything you guys talked about applies except I don't have to shutdown for it to freeze up in my case(although if it's on for long enough and I shut it off it freezes). It freezes up on it's own seemingly at random taking the host with it.

First happened to me on a freshly installed Arch(antergos), then tried it on Debian after updating my kernel from 4.3 to 4.5(there was a bug that made the vm excruciatingly slow before 4.4) and it happened again.

My hardware:

i7 5820k
8GB Ram (Upgrading to 32GB when the ram I ordered gets here)
MSI X99S SLI Plus
AMD Radeon R9-270X (Host GPU using "radeon" drivers)
AMD Radeon HD 6950 1GB (Passthrough GPU)

Interesting that aside from the GPUs(which I'm pretty sure aren't the problem) we all have very similar hardware.

When I get some free time I'll try to replicate this bug on another OS but I have a feeling I'll just get the same result. I just want to see if it'll happen no matter what distro I use.
