not ok 1..1 selftests: ftrace: ftracetest [FAIL]

However it can pass with the upstream tree:
# [28] ftrace - Max stack tracer [PASS]
# [29] ftrace - test for function traceon/off triggers [PASS]
# [30] ftrace - test tracing error log support [FAIL]
# [31] Test creation and deletion of trace instances while setting an event [PASS]
# [32] Test creation and deletion of trace instances [PASS]

So it looks like a test case issue in our kernel tree from this point.

Issue found on B-hwe 5.0 P9 as well.

The first attempt on B-hwe 5.0 P9 does not report failure on the traceon/off trigger.
It's the second attempt complaining it.

Will test again to see what's going on here.

On Eoan, we no longer see the failure for traceon/off triggers ; however,

[45] Register/unregister many kprobe events [FAIL]

Is failing, on arm64. Giving there are so many ftracetests open in the project that are stale, i'm going to close this bug as its originally intended to target against Disco, and re-open a new one for the new failure on Eoan, if in fact is does not align with any of the already existing bugs.
