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. regards, Mario -- I heard, if you play a NT-CD backwards, you get satanic messages... That's nothing. If you play it forwards, it installs NT. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
