Is it also a kernel BUG at [...]/net/core/dev.c:3719, like the
original one, and is the backtrace the same?
Well according to Image_02, it give a kernel BUG at
[...]/net/core/dev.c:3831 , and the backtrace is the same.
Thanks much. Can you try this patch (against a sid or upstream
3.2.1 kernel)?

8139cp: fix missing napi_gro_flush.
The driver uses __napi_complete and napi_gro_receive. Without it, the
driver hits the BUG_ON(n->gro_list) assertion hard in __napi_complete.

Hi
I'm sorry, I tried but it was overwhelming for me, I downloaded the
source and lost it between steps 4.2.4 and 4.2.5.
I'm still novice generally on linux, so I can't test the patch, except
if there is already build kernel with the patch.
Again thanks for your help and patience.
Take care
Ayman
