This issue doesn't exist in VM with a CX3 VF NIC. This happens to the latest stable release of the linux-azure 5.4.0-1023.23 kernel and the latest mainline linux kernel. How reproducible: 100% Steps to Reproduce: 1. Start a VM in Azure that supports Accelerated Networking, and enable hibernation properly (please refer to https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1880032/comments/14 ). Please make sure the VF NIC is CX-4 since the issue doesn't happen to CX-3. 2. Do hibernation from serial console # systemctl hibernate 3. After the VM resumes back, check the MSI interrupt counters in /proc/interrupts for the CX-4 NIC, and also check “ifconfig” (e.g. “ifconfig enP2642s2”) for the RX/TX counters. These counters stop increasing while they should. BUG FIX: The fix is in the net.git tree now: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=19162fd4063a3211843b997a454b505edb81d5ce To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1894896/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
