Looks like malfunction of your card or driver. Is it a new design or is it already working with, say, Windows or something?

Does the above list include your card? Which one is it? Could you show lspci -vv output for that device?

Is is your driver?
Have you tried running the box (with your card) without any unnecessary devices (plugged/loaded)? -- Krzysztof Halasa Network Administrator - 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/
