+	    A bug in the implementation of offline schedulers has
+	    been fixed. The bug was introduced in OTP-R16A/ERTS-5.10,
+	    and caused work-stealing between schedulers to fail. This
+	    in turn, caused work to accumulate in some run-queues.
+	    The bug was only triggered when there were offline
+	    schedulers in the system, i.e., when the amount of online
+	    schedulers was less than the total amount of schedulers.
+	    The effect of the bug got more severe the larger amount
+	    of offline schedulers the system had.</p>
