The issue manifests itself with any x86 server with their in- development PCIe 10GBe LiquidIO NIC.
The card is enabled with a driver that is currently in active development. The issue does not happen in 12.04 LTS nor Centos 7. The coincidence there may be that both do not use VFIO but instead the PCI stub driver to virtualize PCIe NICs. It seems the issue is related to VFIO, which is the method used in 14.04 LTS. The problem manifests itself during card initialization, specifically, when setting up the rings. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563375 Title: A a single PCI read or write appears twice on the PCIe bus.
