With g_ether loaded the sk occasionally becomes 0xffffffff.
It happens usually after transferring few hundreds of kilobytes to few
tens of megabytes. If sk is 0xffffffff then dereferencing it causes

This is a *workaround*. I don't know enough net code to understand the core

Is it happening on SMP or UP ?
UP build, S5PC110
Crash should happen earlier in __inet_lookup_established()
AP
