Well, this looks exactly like my 'signalling/power' issue.
Have a look at my last mail to the 'Strange DMA-errors and
system hang with Promise 20268' thread on the lkm which is
also mentioned on the page you already found.

The role smartmontools plays in this game is the same that
your cronjobs do: they put load on the devices - parallel
load on all of them and thus power consumption increases
and if the power supply works on it's upper border, on-the-
wire signal quality probably decreases.

I pointed this out in a thread 'Logs - ideas what this is
reporting' on the smartmontools-support list too.

Try to exchange power supply, IDE cables and perhaps clean
PCI slots :)
This could be a bit tricky without physical control to the
machine, but you surely will have someone who has :)
Of course, this is just a try - however, I'd bet it helps
in your case.

That's nothing. If you play it forwards, it installs NT.
