+Tails fails to completely shutdown or restart
+---------------------------------------------
+
+When stopping Tails on some hardware, the memory wipe procedure fails to
+complete: the display gets scrambled, but the computer doesn't
+completely shutdown or restart. Sometimes the caps-lock button light of
+the keyboard flashes.
+
+<div class="caution">
+
+When this happens, there is no guarantee that the memory is wiped entirely.
