>Description:
	When booting NetBSD 8.0_BETA on a machine with fdd, just after there're
	fsck checks performed, kernel starts hanging on floppy disk driver
	trying to read from floppy.
>How-To-Repeat:
	Have an old box with floppies.  Boot NetBSD 8.0_BETA.
>Fix:
	No idea.  Mitigate by disabling fd* in boot.cfg.
