Comment 6 for bug 1892131

kernel lockdown is a Ubuntu kernel feature, pm_graph supposed not to read the tracing information when the kernel it's lockdowned.

I would suggest checkbox framework to verify if the kernel is locked down as a resource, and the test job should fail or skip the tests if the test environment is not ready.

I would also like to see a test plan to test the target machine with secureboot and lockdown turned off, so we can still capture the regression with secure boot enabled.
