problem with sleep & ng_socket in FreeBSD 7 prerelease

Hi, All.

netgraph compiled as module
# cd /sys/modules/netgraph
# make depend
# make
# make install
...
# cat /boot/loader.conf
..
netgraph_load="YES"
ng_pppoe_load="YES"
ng_socket_load="YES"
ng_ether_load="YES"
...

This problem pops in time then pppoed starts ppp

uma_zalloc_arg: zone "16" with the following non-sleepable locks held:
exclusive sleep mutex ng_socket r = 0 (0xc182a4d4) locked _at_ /usr/src/sys/modules/netgraph/socket/../../../netgraph/ng_socket.c:484
