Failed with -97 + test code from -106.
Failed with -94 + test code from -106.
Passed with -92 + test code from -106.
So it looks like this issue happens between -92 and -94.
We didn't catch this becuase scobee-kernel was added to the pool since
2024.04.01 cycle but at that time the ubuntu_kselftests_net failed with
deployment error with 5.15.0-106.116.
And then we finally get it tested with -111 in 2024.04.29
** Description changed:
- Issue found with 5.15.0-106-generic
+ 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.
