+We get tons of cases where the master interrupt handler apparently set

+    drm/i915: also disable south interrupts when handling them
+
+Note that there's a regression report in Bugzilla, and other
+regression reports on the mailing lists keep croping up. But no ill
+effects have ever been reported. But for paranoia still keep the
+message at a debug level as a breadcrumb, just in case.
+
+This message was introduced in
