I'm now running the kernel from linux-image-generic-lts-saucy and the issue is still present.
I've just reverted my patched ureadahead from my PPA to the stock one (which is still the same version as when I've opened this bug), removed the pack files from /var/lib/ureadahead and rebooted. No pack files got created.

Reverting now to my patched version.
