update:
After a couple of 'recovery - repair broken packages - reboot' sessions I have the system booting reasonably well, most of the time.
So I'm changing the bug title from 'fails to boot' to 'does not boot reliably'.
I still see errors from udevd about not being able to find dm-6.
Also Grub-pc refusing to find my dmraid partitions blocks me from finishing installing updates to the kernel of adding any new kernel.
