Harald, are you sure the problem you have here is due
to mdadm change and not your new kernel change or even
fstab change?
The thing is that the NMU in question did not change any
stuff in mdadm related to booting. The issue you have
is that after the array gets assembled, it isn't handled
by udev who populates /dev/disk/* directories. In regular
initscript that's done explicitly, but in initramfs it's
not done, and as far as i can see, never had.
Besides, for filesystems on an md array, it's best to use
direct device name (root=/dev/md0) instead of (more modern)
label or guuid, since the device name is stable.
