When I first installed Fedora 20, I had normal boot times. However, sometime over the last few updates, the boot hangs for over a minute before running the kernel. Here is the output from systemd-analyze

Startup finished in 15.312s (firmware) + 1min 24.365s (loader) + 751ms (kernel) + 2.951s (initrd) + 35.199s (userspace) = 2min 18.580s

You can read that the boot takes 1min 24.365s to load the kernel. On the screen, I see that grub starts, displays the boot entries, clears the screen and displays "Booting 'Fedora with Linux 3.14.4-200.fc20.x86_64'. My system then does nothing for a minute and a half, before running the kernel. The Kernel is 3.14.4-200.fc20.x86_64. RedHatGraphicalBoot is disabled, and the system boots to, not graphical. My kernel options are currently
$([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :)

This system is on an ASUS Z-77 motherboard, and boots with UEFI firmware. It dual boots with Windows 7. There are 4 SATA disk drives, all formatted GPT. All pass S.M.A.R.T. self tests. The boot partitions are on the first drive; /boot is a plain ext4 partition and /boot/efi is on a plain fat32 partition. The root filesystem is on an lvm volume comprised of 2 partitions on two drives. The other 2 of the 4 drives are paired into a mirrored dm-raid volume, which is then used as part of a single lvm data partition. That lvm volume has an ext4 filesystem, and is mounted as /home. There are a few additional unmounted partitions, on both the physical and lvm volumes.

Boot once removing quiet option from kernel boot arguments and see where it wastes time.
