Source: linux Version: 5.10.158-1 Dear maintainers, we just upgraded our xen test cluster's kernel to the latest kernel from s-p-u and noticed that network communication is broken. We do have a 'classic' setup with bridges in dom0. After upgrading dom0's kernel, no communication is possible for the domU. We can see packets arrive at the domU and packets leave the domU; but they never arrive at the virtual interface in dom0 (rx counter stays at 0 and error counters stay at 0 too). When migrating the domU back to the other server which has not been upgraded, the machine is reachable again. If there is anything we can do to help fixing that issue, we'll gladly do that! Thank you very much! -- Adi
