Does your swap entry in /etc/fstab have dp in the flags? like this:

/dev/wd0b               none    swap    sw,dp            0 0

Else try 

swapctl -D /dev/wd0b (or similar) to make the named device also a
dump device. You still want to change your fstab so that this will
be active after the next reboot.
