Public bug reported: This instance happened after lockscreen, as such may be suspend-resume related. On the other hand at least 0 and 10 parts on backtrace appear similar to bug #1891636
While this appears to be a recent regression, DpkgLog.txt doesn't contain xorg references. Could it be related to kernel upgrades then, or just happened to slip by undetected after earlier upgrades?
