    I'm seeing the same on 2.6.14.2, also with e1000. It wasn't there on
    2.6.11.12 which I was running previously.

    # dmesg | tail -4
    KERNEL: assertion (!sk->sk_forward_alloc) failed at net/core/stream.c (279)
    KERNEL: assertion (!sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (148)

    # ethtool -k eth0
    Offload parameters for eth0:
    rx-checksumming: on
    tx-checksumming: on
    scatter-gather: on
    tcp segmentation offload: on
