I don't think the network stack is different from vanilla...

I had a different idea:

The media_build process prints:

"Preparing to compile for kernel version 3.4.3913"

In fact, the custom kernel's Makefile contains:

VERSION = 3
PATCHLEVEL = 4
SUBLEVEL = 39
EXTRAVERSION = 13
NAME = Saber-toothed Squirrel

Is it possible that the build process gets confused by the EXTRAVERSION field?

Regards.
