Ok, I found the problem. Your broken initramfs image is missing the ORDER files. All initramfs images that work fine have the ORDER files.
There are _three_ codepaths in the initramfs script/functions: one wants the ORDER files (which are missing in your initramfs image), the other wants tsort (which is unavailable in the initramfs), and the third one is obviously broken. Now, I have no clue why your systems do not generate the ORDER file, this is likely a second problem in the initramfs-tools package, but intel-microcode is somehow triggering it on your system. This is the only reason I haven't reassigned this to initramfs-tools yet. Can you try to debug a run of update-initramfs ? See if you can track down why it is not creating the ORDER files on your system. The ORDER files are created by /usr/share/initramfs-tools/hook-functions. You will likely have to edit update-initramfs and/or hook-functions, and add "set -x" where required to get some decent debugging output :( -- "One disk to rule them all, One disk to find them.
