    I tried raising KVA_PAGES to 512 a couple of hours ago, as the panic
    seemed to suggest running out of KVA, and it seems to have resolved it.

    I haven't touched the VM_KMEM_SIZE/VM_KMEM_SIZE_MAX options, however.
    Reading the LINT notes, this seems unrelated... Are you sure that's a
    necessary change?

    Also, for the maintainer of "man tuning", perhaps KVA_PAGES should be
    documented as servers with >2GB of ram are only becoming more popular
    -- hell, I have 3.5GB of ram in my workstation nowadays...
