Completely disabling ACPI rarely works with modern machines.

Please try to run the following DTrace script (dtrace -s script-file) and
capture its output.

#pragma D option flowindent

fbt::acpi_intr_handler:entry
{
	self->trace = 1;
}

fbt:::entry
/self->trace/
{
	printf("arg0 = %#x, arg1 = %#x, arg2 = %#x", arg0, arg1, arg2);
}

fbt:::return
/self->trace/
{
	printf("_at_%p ret = %u", arg0, arg1);
}

fbt::acpi_intr_handler:return
{
	self->trace = 0;
	exit(0);
}
