The md5sum doesn't match those of the version installed on your system. This is probably a result of the problem with your freeze issue.
Copy the files /var/lib/dpkg/info/ureadahead.* to some location for history.
remove the file /var/lib/dpkg/info/ureadahead.triggers
and run
$ sudo dpkg --purge ureadahead
If it fails with post-removal script then remove that file too.
then clean your cache
$ sudo apt-get clean
and try performing the install of ureadahead again.
