You need to rebuild the kernel. Add the following line to kernel
configuration:
options ACPI_DEBUG
Then, type this from loader prompt:
set debug.acpi.layer=ACPI_ALL_COMPONENTS
set debug.acpi.level=ACPI_LV_ALLOCATIONS
boot
You will be able to trace all refcount changes. Once it boots, login
and do this to turn it off:
sysctl debug.acpi.layer=NONE
However, I am afraid it will spit out too much information for you to
interpret the data. :-(
