It's hitting an ASSERT_RTNL in netif_set_real_num_tx_queues(), looks like igb_runtime_resume() thinks it doesn't need RTNL, as rpm == true in the call to __igb_resume() from igb_runtime_resume(). I'm not sure why it's written that way since the call to set the queues is unconditional in __igb_open().
Looks the same upstream as well, the issue presumably manifests due to runtime power management first suspending then resuming the device.
