update-initramfs stuck in hooks/framebuffer (linux-image-3.2.0-23-generic 3.2.0-23.36 failed to install/upgrade)

update-initrafs is stuck with 0% CPU usage. (the exit status is because I killed it manually to make the installation complete)

This is a piece pasted from htop's tree.

This happened during a routine upgrade of precise today, with last dist-upgrade about one week ago. The error persists with subsequent "apt-get -f install" runs.
