The kernel oops below occurred due to incorrect error handling flow when pci_setup_device() fails.</p> <p>Add pci_iov_scan_device(), which handles virtfn allocation and setup and cleans up if pci_setup_device() fails, so pci_iov_add_virtfn() doesn&#39;t need to call pci_stop_and_remove_bus_device().
