Thanks. > On second thought, I think your original patch should be sufficient and we don't need to add the PCI quirk to cover so many devices. The reason is that indirect access needs to be explicitly enabled in the MISC_HOST_CTRL (0x68) register. The default value for register 0x68 should have indirect access disabled.

Did you ever see any system crash before tg3 loads? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
