Bug#766385: Generating /boot/initrd... seen twice in a single aptitude full-upgrade
some more context probably helps:
...

/etc/kernel/postinst.d/dkms:

so it would appear that the mistake is that the kernel postinst does an
instantaneous initramfs update, rather than letting the trigger take
care of it, after DKMS has built the modules of other upgraded packages.
it may also make sense to sequence the grub setup after the initrd
setup, so it doesn't register kernels for which building the initrd
failed.
