Almost.. I indeed managed to complete the upgrade by following the
suggestion in comment 17 in the bug above: There are no more packages
to configure/update/install.

However, I'm still unable to boot Precise. Using default kernel
parameters (for 3.2.0) I get the following messages:
[..]
Begin: Running /scripts/init-bottom ... done.
could not log bootup: Address already in use
[ 10.1 ] init: plymouth main process (327) terminated with status 69
mount: Too many levels of symbolic links
mountall: mount /run [349] terminated with status 32
mountall: Filesystem could not be mounted: /run
An error occurred while mounting /run.


Then I press S to skip mounting and I get the following:
The disk drive for / is not ready yet or not present.
Skipping /run at user request
udevd[359]: error: runtime dir '/run/dev/' not writable, for now
falling back to '/dev/.udev'


Next I press M for manual recovery and get this:
Root filesystem check failed.
A maintenance shell will now be started.


All this looks strange to me, as I force checked / (and all other FS)
and they're all clean. I'm wondering though if after installing all
the packages there were some Precise-specific scripts that didn't get
executed to prepare the new OS. Among other things, perhaps /etc/fstab
didn't get updated? (Here's my current /etc/fstab:
http://paste.ubuntu.com/1191361/ )

Should I run 'do-release-upgrade' again?
