Found on: d2021.10.26/jammy/linux-realtime/5.15.0-1004.4 (appleton-kernel.arm64)

[Po-Hsu Lin (cypressyew)]

Can be found on Jammy OEM-5.17 as well.

[Po-Hsu Lin (cypressyew)]

This issue can be found with Kinetic kernel as well.

[Utkarsh Gupta (utkarsh)]

Ubuntu 22.10 (Kinetic Kudu) has reached end of life, so this bug will not be fixed for that specific release.

[Po-Hsu Lin (cypressyew)]

This issue has gone on Jammy+, but still visible on Focal 5.15 variants.

[Po-Hsu Lin (cypressyew)]

This might need iproute2 update mentioned in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1961566/comments/2 as well.
