+Subject: [PATCH] Prevent the UI from locking up while the countdown runs
+
+struct status has 4 parameters. Provide values for all of them
+so that random values are not used instead.
+
+Visible on an ARMv7 device as a "hang" (ignoring input) when the
+countdown starts, after things have been probed.
