You can add a fourth.  Ever since 5.1 (my first 5.x install) I have
experienced the same problem, again with an Intel ICH5 ATA controller.
The symptoms are exactly the same -- the hang is normally triggered
during the periodic runs just after 3AM.  The hang does occur at other
times as well, but with nowhere near the same consistency.

The only solution I found at that time was reverting to 4.10, though
that is obviously suboptimal.  I could be persuaded to reinstall 5.x
on the machine if I'd be sure to get someone to look into this.
