SRU submission: https://lists.ubuntu.com/archives/kernel- team/2020-October/114296.html ** Description changed: + [Impact] + Description of problem: In a VM with CX4 VF NIC on Azure, after hibernation/resume, the TX/RX packet counters stop increaseing. 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. + + [Test Case] 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. + [Regression Potential] + + The change touches netvsc and has potential to affect any instances + using accelerated networking. However the fix is straightforward and + it's a clean cherry-pick from 5.9. + + [Other Info] BUG FIX: - The fix is in the net.git tree now: + The fix is in the net.git tree now: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=19162fd4063a3211843b997a454b505edb81d5ce ** Also affects: linux-azure (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-azure (Ubuntu Focal) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894896 Title: [linux-azure][hibernation] Mellanox CX4 NIC's TX/RX packets stop increasing after hibernation/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1894896/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
