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. PCI ASPM, maybe? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083151 Title: igb assertion changing rx/tx queues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-lowlatency/+bug/2083151/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
