Xorg.log with crash

Hi there,

I'm getting some random X crashes using I V O, I have no idea how to reproduce them, but is under daily regular usage, and is like 1 each 3 days.

Steps to reproduce? :
1) Enable I V O with Nvidia and primus.
2) Use the desktop
3) Crash under a desktop intraction.

Version of xf86 intel: 2.99.917_p20161118 with Bug 98855 patches.
Version of Xorg: 1.19.0
Version of Mesa: 13.0.2

OK, after couple of weeks, I can reproduce this issue 2 or 3 times at day, only using external monitor it looks like.

I still not getting an standard way to reproduce this. There is some better way to provide enough data to analyze? Using X with gdb or the current Xorg.log is enough to understand the problem?

I'm still able to reproduce this bug, but I still not have any common pattern of how reproduce it. Looks like randomly after some input event it got restarted.

There is some way I can help to provide more info about it? It might crash zero times on a day, or might crash +3 times on a day doing the same kind of tasks.

This is reproducible on both 4.8 and 4.9 kernels.

I can confirm this doesn't only happen with I V O, I had a crash without using intel-virtual-output about that.
