Will that enable a 64GB dump? In 8.1, dumpon(8) says:
The dumpon utility is used to specify a device where the kernel
can save a crash dump in the case of a panic.
...
For most systems the size of the specified dump device must be
at least the size of physical memory.
...
The dumpon utility will refuse to enable a dump device which is
smaller than the total amount of physical memory as reported by
the hw.physmem sysctl(8) variable.
Note the use of the singluar: "a device" and "the specified device".
