hang1.jpg looks like it didn't even start booting into the system and it's stuck in initramfs during kernel boot. I had such a case this morning on my computer, it would consistently fail to boot with the new 3.19.0-8 kernel. Booting with the previous 3.19.0-7 or upgrading again to 3.19.0-9 worked, though. To test that, can you choose the previous kernel in grub (-7) and see if that looks different? You can add "break=bottom" to the kernel command line to get an initramfs-tools shell right before it would start to boot the real system. If it doesn't even get that far, it's very likely a regression in the kernel.
hang2.jpg did get into the real system. For that, can you boot with a debug shell (see /usr/share/doc/systemd/README.Debian), do "journalctl -b > /root/journal.txt, and attach /root/journal.txt here?
