net:tls fails on Mantic lowlatency in openstack with a sut-test failure with no explained error despite having been re-run multiple times.

We will need the kernel version for this bug.
Marking this as Incomplete.

This occurred on cpu2-ram4-disk20.arm64 lowlatency.

[Po-Hsu Lin (cypressyew)]

OK, I have checked the test history on M-lowlatency 6.5.0-25.25.1 openstack ARM64

This test has failed on the 3rd attempt on jenkins, the ubuntu_kselftest_net ran about 43m31s and the instance disconnected when running the tls test.

On the 4th attempt, the ubuntu_kselftest_net ran about 54m44s and disconnects when running pmtu.sh test (tls passed in this round)

So I think this bug is invalid. To dig deeper we might need to start an instance and run these tests manually to see what's going on (console output collected on jenkins is not helpful).
