-The plugins stuff has got obscure problems on PPC64 ... figure it out
-another day ...
+The plugin_load test fails on PPC64 (maybe not always, but at least in the
+several tries I've made so far).  It doesn't fail on x86, x86_64, or ppc,
+at least not in a similarly small number of tries.  My best theory at the
+moment is that the test itself is wrong.  Reported upstream at
+http://bugs.mysql.com/bug.php?id=42144
+
+For the moment, just disable this test.
