kernel hang when reboot with loaded ip_vs_rr.ko

[Sam Wun]

It is IPVS patch, for FreeBSD.
I am in Melbourne Australia.
Can you send me email regarding about how to fix this issue?
BTW, if I kldunload ip_vs_rr before reboot/shutdown, the system will
execute the reboot / shutdown normally.
When I executed reboot/shutdown with the ip_vs_rr still loaded in the
kernel, the system hangs after the console printed the message
"...vnode...."

Here are the modules loaded:
# kldstat
Id Refs Address    Size     Name
 1    5 0xc0400000 a434d8   kernel
 2    1 0xc0e44000 6a45c    acpi.ko
 3    1 0xc469d000 2000     ip_vs_rr.ko
 4    1 0xc469f000 b000     ipvs.ko

 # shutdown -h now
.....
Syncing disks, vnodes remaining... 1 1 0 0 done
All buffers synced.
IPVS: ipvs unloaded

then it hangs forever.

Another problem is I can't put ipvs_vs_rr_load="yes" in the
/boot/loader.conf file. The system will hang when it tried to boot the
kernel with this ko loaded.

Thanks
