Hi Si-Wei, the 5.11 kernel has reached EOL in Feb 2022. Kernel 5.15 is the one currently being used for linux-oracle kernel on Focal (20.04) and Jammy (22.04), and it has the commit that you mentioned above:
$ git log --oneline | grep -i "Fix page DMA map/unmap attributes" a865fe280b96 net/mlx5e: Fix page DMA map/unmap attributes $ git tag --contains a865fe280b96 Ubuntu-oracle-5.15.0-1001.1 Ubuntu-oracle-5.15.0-1001.2 Ubuntu-oracle-5.15.0-1001.3 Ubuntu-oracle-5.15.0-1002.4 Ubuntu-oracle-5.15.0-1003.5 Ubuntu-oracle-5.15.0-1004.6 Ubuntu-oracle-5.15.0-1005.7 Ubuntu-oracle-5.15.0-1006.8 Ubuntu-oracle-5.15.0-1007.9 Ubuntu-oracle-5.15.0-1009.12 Ubuntu-oracle-5.15.0-1011.15 Ubuntu-oracle-5.15.0-1012.16 Ubuntu-oracle-5.15.0-1013.17 Can you test a guest running 5.15 to see if this addresses the problem? Regards, Fabio Martins -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oracle-5.11 in Ubuntu. https://bugs.launchpad.net/bugs/1980884 Title: ubuntu guest kernel panics when a sev guest with passthrough mlx5 VF is used Status in linux-oracle-5.11 package in Ubuntu: New Bug description: Guest kernel panic can be observed when Ubuntu SEV guest with mlx5 vfio-pci is started as iperf3 server using "iperf3 -s" and as soon as the client tries to connect with it.
