You could try building with DEBUG=nii:3. If you are seeing the same

DEBUG=nii:3 does not create any additional output for me.
Trying to understand the code a little more, where is the
bs->CreateEvent function pointer set exactly?
'git grep "CreateEvent"' seems to show me executions of that
pointer only.
The function that we hook to get called at the time of
ExitBootServices() is efi_shutdown_hook() (in efi_init.c).
From there, you can try tracing the execution through the call to
shutdown() to see which shutdown methods get called. You might find it
helpful to look at the linker map (add ".map" to the end of your build
target) to track down the constructed startup_fn array: the shutdown
functions get called in the reverse order of this array (and any NULL
entries will not be called).
