https://bugzilla.kernel.org/show_bug.cgi?id=42635 Summary: PCIe passthrough broken with AMD iommu after s2disk / resume Product: Virtualization Version: unspecified Kernel Version: 3.1 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: kvm AssignedTo: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx ReportedBy: kmueller@xxxxxxxxxxx Regression: No A PCIe ethernet device is passed through to the guest and runs fine. Some time later, the guest is shutdown (e.g. virsh shutdown guest) and the host is suspended (s2disk) and resumed again. The guest is started again (and it starts fine), but the device in the guest isn't working any more (it can be seen, it can be pinged itself but nothing is reachable outside the device. The rx or tx counters of the ifconfig output are always 0. If the guest is shutdown and the device is bound to the host, it's working as expected. If the device is afterwards bound to the guest again, it doesn't work as before in the guest after resume. kernel: 3.1 / 64bit / smp kvm: 1.0 board: GA-990XA-UD3 If you need more information, I can provide them - feel free to ask!
