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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
