The "re-exe init" is caused by /etc/cron.daily/prelink being run.
It ends by restarting init.  You can disable it by renaming
prelink -> prelink~  .  The "run-parts" script ignores files that
end in "~".  If it no longer freezes, its from the prelink script.

You can also run the script by hand to see if it induces an immediate freeze.
