Hmm I don't have a riser card and I don't have a setting for the frequency, nor a jumper. I plugged the card in another slot, next to a 66MHz only card. So now I've it working with 66MHz (checked with lspci), but my drive isn't initialized properly anymore: [4294690.486000] libata version 1.20 loaded.

I get the same error on every reboot. Jan ps: the raid survived :-), though it's obviously missing one disk now. - : send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
