archiso built today: Initramfs unpacking failed & Kernel panic... VFS

(First, yes, I'm running ./build.sh as root as the instructions suggest to avoid permissions problems.)

I brought an arch system up to date, rebooted, and made a new archiso by:

cp -r /usr/share/archiso/configs/releng/* .
./build.sh -v

The ISO was made fine.  I didn't make any changes to the default releng files.  I will be, but I'm just starting with no changes to make sure that works first.

(Typing by hand, so kernel uptimes omitted)

dmi: Firmware registration failed.

I see topic 207994 from yesterday isn't using a new archiso, but is getting the same Kernel panic... VFS.  No idea if that's related.

I've re-made the ISO 3 times to make sure there isn't some random corruption going on.

On the system I made the ISO, I can:

# mount -o loop new.ISO /iso
mount: /dev/loop1 is write-protected, mounting read-only
# xzcat /iso/arch/boot/x86_64/archiso.img | cpio -vid
<snipped lines showing all the files>
186007 blocks
# xz --test /iso/arch/boot/x86_64/archiso.img
{{{ returns saying nothing, passing the archive's integrity test }}}

And it has no complaint.  Not sure where the "Initramfs unpacking failed: junk in compressed archive" is coming from.

If I boot off the released archlinux-2016.01.01-dual.iso, it works just fine.

Is the released archiso at the beginning of every month created by the archiso releng files, without modifications?
