Panic: attempted pmap_enter on 2MB page

[Dave Hayes]

What does the above mentioned panic mean? I'm booting from
an mfsroot off of a DVD with a loader.conf like this:

 autoboot_delay="5"
 mfsroot_load="YES"
 mfsroot_type="mfs_root"
 mfsroot_name="/mfsboot"
 vfs.root.mountfrom="ufs:md0"
 vfs.root.mountfrom.options="rw"
 kern.ipc.nmbclusters=32768
 net.inet.tcp.tcbhashsize=16384
 vm.pmap.pg_ps_enabled=1
 vm.kmem_size="2G"
 accf_http_load="YES"
 net.inet.tcp.syncache.hashsize=1024
 net.inet.tcp.syncache.bucketlimit=100

This is FreeBSD 8.1-RELEASE amd64 running with the debugger installed
into the kernel. Thanks in advance for any insight provided. :)
