Downgrading to 17.2.6 on Arch fixed the issue for me as well. - Everything runs without any problems as soon as INTEL_DEBUG=norbc is set. However, for me the GPU hang always occurs already a bunch of seconds after starting Xorg. Currently, I have not yet made the effort to do a git bisect. I append my dmesg log und and GPU crash dump in the hope to give further hints. If I can help further, just tell me and I will try to do so.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
