Running update-grub should update grub.cfg. Installing new kernel failed to configure grub.cfg:

Investigating the update-grub call I find that
  grub-probe --device /dev/mapper/vg.sys-lv.dapper --target=abstraction
is failing with a Segmentation fault.

I have my pv's on raid1 drives. I've recently added another pair (sdc and sdd):

Today I ran the Lucid live CD. grub-probe from the CD does not exhibit this behaviour.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Phillip Susi (psusi)]

Lucid is end of life and no longer supported; are you able to reproduce this on a currently supported release?

[Expired for grub2 (Ubuntu) because there has been no activity for 60 days.]
