I'm adding e1000-devel and intel-wired-lan as they would be a better place for an ixgbe question. It might be useful if you could also provide an "lspci -vvv" for the system, or at least for the network ports so that we can verify if enough resources are present in terms of memory to allocate memory for MMIO on all the devices. Also any info you could provide on the platform itself would be useful as it is possible what you are seeing is a resource constraint as the GSI error seems to indicate ACPI is having some sort of issue. - Alex ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
