I never got such outputs when crash happened.

It seems the crash only happened when high workload， but I am not sure about that.

The bios I used also had some problems(I guess) with VTD and iommu, I also not sure is this issue relate to bios or not.

You can have a try to build xf86-video-intel with "--with-default-dri=3". at least, after default to dri3, there is no crash here.
