Comment 12 for bug 491943

Also seen on a 2GB machine with the server kernel.

Note that you can do an:

    apt-get --purge remove ureadahead

as a workaround, with largely no ill effects, if you aren't relying on any of its functionality directly.

This will remove the meta-package ubuntu-minimal, so once this bug is fixed, you can do

    apt-get install ubuntu-minimal

to get back ureadahead and the meta package at the same time
