It's not very convenient to recompile the kernel for testing purposes. Unless you recommend this to be turned ON by default, even in production builds? Even with this option turned on, manually restarting video playback is still for now the only known, slow and elusive way to reproduce this hard crash. There seems to be a tentative root-cause so could some (new?) lower-level and more focused (IGT?) test(s) stress overlays harder, better, faster and stronger?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
