Sadly, no joy with `tm4c129e-launchpad:ostest` (+
`CONFIG_PRIORITY_INHERITANCE=y` added manually) either.
Although `b-g474e-dpow1` is STM32 and `tm4c129e-launchpad` is Tiva, they are
both armv7-m. However, they seem to be crashing in different parts of the test.
I am beginning to wonder if the problem is not in priority inheritance, but
in something else that is manifested because of conditions created in the
priority inheritance test.
Below is the log.
