Package: src:linux Version: 4.9.110-3+deb9u4 Severity: critical Hi,
For network testing reasons I run several KVM VMs with up to now four virtio NICs, where only one NIC is connected and the others are marked as "link_down" in the KVM configuration. In the guest the NICs are configured as bonding device with lacp. Up to linux-image-4.9.0-6-amd64 this worked without issues. Starting with linux-image-4.9.0-7-amd64 the kernel now reports after booting: Aug 27 12:01:39 test-gate-1 kernel: [ 22.881163] bond0: link status up for interface ens18, enabling it in 0 ms Aug 27 12:01:39 test-gate-1 kernel: [ 22.882881] bond0: failed to get link speed/duplex for ens18 Aug 27 12:01:39 test-gate-1 kernel: [ 22.985209] bond0: link status up for interface ens18, enabling it in 0 ms Aug 27 12:01:39 test-gate-1 kernel: [ 22.986998] bond0: failed to get link speed/duplex for ens18 Aug 27 12:01:39 test-gate-1 kernel: [ 23.089250] bond0: link status up for interface ens18, enabling it in 0 ms Aug 27 12:01:39 test-gate-1 kernel: [ 23.091765] bond0: failed to get link speed/duplex for ens18 Aug 27 12:01:40 test-gate-1 kernel: [ 23.193170] bond0: link status up for interface ens18, enabling it in 0 ms Aug 27 12:01:40 test-gate-1 kernel: [ 23.195772] bond0: failed to get link speed/duplex for ens18 ethtool also shows unknown speed and duplex for the virtio interfaces. This seems to not have been an issue before linux-4.9.0-7. Switching the virtual NICs from virtio to vmxnet3 solves the issue, ethtool also reports speed and duplex mode. I do not know if this is a KVM issue or a kernel issue, but as the older kernel image works it looks more like a kernel issue to me. -- Package-specific info: ** Kernel log: boot messages should be
