Ok I did some additional debugging.

update-initramfs -u -k 3.10.0-3-generic:
3.10.0-3 still boots fine, so update-initramfs doesn't break it.

update-initramfs -u -k 3.10.0-4-generic:
Neither does it fix the problem on -4 kernel

boot arguments:
The defaults are:
linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash modeset=1 pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 $vt_handoff

When changing it to:
linux /boot/vmlinuz-3.10.0-4-generic root=UUID=af3a67b1-5cbf-48f1-b0b7-0848ae3017b4 ro quiet splash $vt_handoff
the -4 kernel boots fine ...

What I also noticed it the following error:
[ 23.139890] kvm_intel: Unknown parameter `nested'

This does NOT happen on -3 kernel. So it seems like modprobe or so is broken for -4 kernel?!
