#12654: Unexpected IP address change

-----------------------+----------------------------------------------------
When trying to do wake on LAN testing of XO-4 laptops (with 8787 wireless
cards, i.e. the mwifiex driver) using os3, I cannot get them to operate
for more than a few hours. Unlike other laptops connected to the DHCP
server, they change their address every few hours.
This is 100% repeatable when using the following test procedure: 1)
Install os3. 2) Boot into os3, and "touch /etc/powerd/flags/inhibit-
suspend". 3) Associate the laptop with an open AP. 4) Determine the IP
address.
From another laptop, start this script running (as root):
while sleep 30 ; do date -u && ping -c 20 -i 0.01 <ip_address> ; done
Run the following on the test laptop:
ethtool -s eth0 wol u && while date && rtcwake -m mem -s 60 && date &&
sleep 12 ; do : ; done
Pinning the ARP table on the pinging laptop (using arp -s <ip_address>
<mac_address>) doesn't have any effect on the problem, as it is the actual
IP address on the test laptop which is changing. Network Manager is
running during this test.
