hi,

I have exactly the same issue on my Galaxy Axe. I also tried Wayland cm9.1, and 
Maclaw aosp, and  issue remains. I also saw in xda some other people who have 
the same issue, on CM10.1, on Mini or Gio.

I think I found the cause of this issue. The problem is in the code parsing 
netlink messages, which is used by netd. It seems that netd gets stuck in 
infinite loop as soon as it receives buggy netlink message. I've created a 
patch to avoid that, however it needs more testing and possibly some refining.

The patch should be applied on a CM9 source code before build a rom. Here is a 
compiled libsysutils.so for Galaxy Gio using the MMB CM9 source tree and above 
patch. Anyone brave enough may replace the original library with this one. Of 
course I'm not responsible for any bricked phone :)
