So to reconfirm, you now run 1.1.2, which is fine?
The earlier error report was when you use 1.1.3?

It should. If not, then it's a bug.

This is where a test system would be handy.
If you're willing to contribute some effort, you could setup another
machine (or, VM. 1GB memory is more than enough), setup a similar
system, and at least verify whether or not the errors with 1.1.3 and
precise is reproducable. You'd going to need it anyway if you're going
to follow Serge's troubleshooting steps, since I believe it should be
run on 1.1.3.
... and for the record, I'm not a developer, so this would most likely
be my last reply to this thread.

Good catch with the backup plan.
If you use btrfs or zfs root, there's also alternate root setup with
snapshot/clone that would help in this situation, but that's a
different story for another time.
