"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
