+	On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into
+	kernel modules.  Therefore, if you load any kernel modules at boot time,
+	please install the boot loaders after you install the kernel, but before
+	rebooting, e.g.:
+
+	make buildworld
+	make kernel KERNCONF=YOUR_KERNEL_HERE
+	make -C sys/boot install
+	<reboot in single user>
+
+	Then follow the usual steps, described in the General Notes section,
