Xen: 4.4.2-pre (28573:f6f6236af933) + xsa111, xsa112, xsa114 Dom0: 3.17.4 We recently moved our dom0 from 3.10.x to 3.17.4, in order to avoid a netback host crash that has been plaguing us. After doing so, the new multi-queue netback stuff constantly on/offs carrier on the vif, spamming the console, and making the bridge device leave forwarding state and then immediately reenter forwarding state.
