Got another system with the symptoms and managed to get a snapshot.
It is really extremely weird. The kernel output is
List of all partitions:
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
This is reproducible. To fix it it is enough to boot into the Wheezy
kernel (even with init=/bin/sh), then reboot. It apparently does
something to the root-fs (fsck?) which allows the Jessie kernel to boot.
I have asked our Windows guys to make a screencast, it is uploaded here.

We still have the snapshot available, if you have an idea please drop me
a note.
