+	The uart(4) driver has been changed with respect to its handling

+	any process from changing the baudrate or the CLOCAL and HUPCL

+	associated with the low-level console, a misconfigured terminal
+	line in /etc/ttys will now have a real impact.
+	Before upgrading the kernel, make sure that /etc/ttys has the
