 "TUNABLE_INT" defines a loader tunable, not a sysctl variable.  To
 set the value, you need to enter the following line in the loader(8)
 prompt or put it into /boot/loader.conf:

 debug.acpi.max_tasks=32

 A kernel configuration file can include this option.  The following
 should also work:

 options	ACPI_MAX_TASKS=32
