Hi, whenever I try to start a KVM VM with 'Qualcomm Atheros AR9580 Wireless Network Adapter' assigned it will immediately reboot the host. I've tried already a couple of things:
1. Played with module parameters. vfio_pci nointxmask=1 vfio_iommu_type1vfio_iommu_type1 disable_hugepages=1 2. Tried kernel 4.4, 4.6 and 4.8rc1.r2.g574673c2 3. Tried all different PCIe slots in the system. It is a dual socket system with 6 PCIe slots, where 3 are connected to CPU1 and 3 to CPU2. I don't have any clue what the root cause could be. I have tried another Wireless card which works fine with VFIO passthrough. It was some old D-Link PCIe model but with different chipset. Any help would be much appreciated to narrow down the problem. The system itself has the following configuration: - Supermicro H8DG6/H8DGi - 2x Opteron 6366 HE - IOMMU is enabled in BIOS. - VFIO uses the following devices: 02:10.0-02:10.7 02:11.0-02:11.5 05:00.0 (not working) 41:00.0 42:00.0 lspci output: 00:00.0 Host bridge: Advanced Micro Devices, Inc.
