Bug Description

On booting vexpress (A9 or TC2) I see a SIGSEGV in the DHCP Handler Thread (see attached logcat.log).
This takes down the system server and results in continuous reboot attempts.

If I remove the network cable then boot succeeds. If I then re-insert the cable and go into the Ethernet Connection Manager settings and turn ethernet off then on again, then I gett he same crash.

Observed in build https://android-build.linaro.org/builds/~linaro-android/vexpress-jb-gcc47-armlt-tracking-open/#build=33
The later build 34 also has the problem, and earlier build 31 is OK.

The patch which caused this problem on vexpress was reverted, so from the ARM LT point of view this bug has been fixed. (The reverted patch was to fix Panda and so there may still be an outstanding bug in that area.)
