Comment 3 John W. Linville 2010-12-03 18:58:22 UTC 
What kernel are you running?
Comment 4 filippo 2010-12-03 22:24:44 UTC 
2.6.36. Should i update it?
Comment 5 John W. Linville 2010-12-06 19:53:58 UTC 
config NETWORK_PHY_TIMESTAMPING
        bool "Timestamping in PHY devices"
        depends on EXPERIMENTAL
        help
          This allows timestamping of network packets by PHYs with
          hardware timestamping capabilities. This option adds some
          overhead in the transmit and receive paths.

          If you are unsure how to answer this question, answer N.

In the shortrun, you might try turning that off in your .config.

Wey-yi, it looks like iwl3945 isn't leaving enough headroom in the skb for the skb_push in skb_defer_rx_timestamp?

The following three bugs are all duplicates of each other:                      
                                                                                
  24102                                                                         
  24292                                                                         
  24452                                                                         
                                                                                
They all have the same root cause, and all are fixed by the patch

   http://article.gmane.org/gmane.linux.network/180108                          
                                                                                
The work-around is to disable CONFIG_NETWORK_PHY_TIMESTAMPING.
