attached both



Ok, so according to your dm= esg, heap initialization is disabled:
=C2=A0 mem auto-init: stack= :all(zero), heap alloc:off, heap free:off
, which causes the test= failures.

The warnings indeed originate from=C2= =A0CONFIG_TEST_REF_TRACKER=3Dy, and seem to be yielding the desired output = for that test (ccing Eric who wrote it).
Perhaps that test could = print something about its expectations to dmesg, but anyway=C2=A0there'= s nothing to fix in the kernel.

May I ask what is = the purpose of the config in question?
