*
* - Submit an ISR request during system initialization. Check the stack of
* the interrupted context while the ISR request is serviced. Store the
* result of the check in interrupted_stack_at_multitasking_start_is_valid.
*
* - Check that stack of the interrupted context was valid when an interrupt
* was serviced during the multitasking start.
