I'm not so sure the motherboard is broken, I am leaning more towards a misconfigured bridge. This computer is a 4U 19 inch rackmount chassis with a PCMIG CPU and a 12 slot PCI backplane. I have done a lot of testing with this box trying to characterize this problem. In one case I have put 3 Intel PRO 100S NICs on the secondary PCI bus and they ran under heavy stress test loads overnight. The 4 port NIC seems to be the only card that doesnt want to cooperate. - 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/
