I had similar problems in the past, but with the latest version of drm-next-4.17-wip (09695ad78f1f) PLUS the backlight patch in <a href="show_bug.cgi?id=104064#c34">comment 34</a> applied on top of that, my system is now very nice and stable! So maybe try that out and let us know how it goes?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
