I am sure this is not a bug, looks like the board is enabling all kind of options that most likely have some kernel objects, so the counting does not match.

[nashif]

this is not a bug, the PS2 and other IPs being enabled by default add objects and the count does not match anymore, so the test fails. Boards should by default only enable the bare minimum, all optional features should only be enabled by the application using them, and not by default for every configuration

The current number of threads "10" did not matched the expected "9". The kscan driver has a thread which is messing with the expected count. The test passes after disabling it ... I'm going to create a PR for disabling the KSCAN in the board.

#22816

[ashaannajoy]

This test passes by disabling KSCAN in zephyr/boards/arm/mec15xxevb_assy6853/mec15xxevb_assy6853_defconfig

[nashif]

#22921 has a more generic fix that should work with pre-existing conditions. Please verify.
