>Description:
"newfs_lfs -A" always causes "pmap_unwire: wiring for pmap 0xcb109be0 va
0xbfbee000 didn't change!" kernel error message.

pread() at line 125 in sbin/newfs_lfs/newfs.c is the point to cause this.

# newfs_lfs -A /dev/rwd0e
Floating point exception (core dumped)

Without "-A" option, it is OK.
