I'm wondering if the upstream change "Fix locking in SRIOV mode of mlx4 driver, from Jack Morgenstein" might fix this issue. It's part of this merge to Dave Miller's tree, and later to 5.1: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/ethernet/mellanox?h=v5.2&id=f3ca4c55a6581c46e9f4a592dd698a7c67a713dd

Unfortunately this issue doesn’t have a 100% repro. Sometimes all the VFs are missing, other times a few are available and the rest are missing. The best test case to catch this issue is VERIFY-ENABLE-DISABLE-SRIOV- ON-EXISTING-VM. Comparing the logs between working/not working VMs, the only difference was that these 2 messages were missing from the broken VMs: mlx4_en: rename9: Steering Mode 2 mlx4_en: rename9: Link Up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1831268/+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
