Title:
  rtnetlink.sh test in ubuntu_kselftests_net cause kernel panic on ARM64
  node scobee-kernel with J-5.15

Status in ubuntu-kernel-tests:
  New
Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Jammy:
  In Progress

Bug description:
  Issue found with 5.15.0-111.121, verified manually with
  5.15.0-106-generic

  When running the rtnetlink.sh test from ubuntu_kselftests_net, it will
  cause kernel panic on ARM64 node scobee-kernel.

  Reproduce rate is 100%, just run the rtnetlink.sh from the Jammy tree.

  Test log:
