The error is not easily reproducible but shows up quite randomly after intense use of Chrome, however I've run the laptop for 2 days with "i915.enable_execlists=0" and it did not show up. Reboot once without it, and after one suspension I got the error again. So the option likely solved it. After 2 days with "i915.enable_execlists=0" I found only this instead: [ 8171.802098] PM: Entering mem sleep [ 8171.802110] Suspending console(s) (use no_console_suspend to debug) [ 8171.803545] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 8171.807718] sd 0:0:0:0: [sda] Stopping disk [ 8172.835579] [drm:stop_ring [i915]] *ERROR* render ring : timed out trying to stop ring [ 8173.267949] PM: suspend of devices complete after 1464.521 msecs which seems to be related with the beginning of suspension and did not cause any freeze nor crash. Also, I have now thousands of "Unclaimed register detected" messages. Not fatal nor problematic, just annoying for filling the log. Not sure if related or not.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
