I just had the same problem, and it turned out I was not diligent when I
first set my zfs pool up :)
To use vm.kmem_size="512M" you need to put
options KVA_PAGES=512
in your kernel. I remember trying the loader.conf settings on a GENERIC
kernel, found it worked and forgot to add KVA_PAGES. It seems that
recently the memory allocated by a ZFS kernel on startup has become
larger than the default KVA_PAGES in GENERIC.
Hope this helps,
