    Subject2.6.17-mm4 + hostap + pcmcia + lockdep -- possible recursive locking detected -- (af_callback_keys + sk->sk_family#3){-.-?}, at: [<c119d8db>] sock_def_readable+0x15/0x69
    I have patches for hostap, pcmcia and lockdep applied to this kernel.
    These patches are the ones resulting from several recent message
    I just noticed this in my kernel log:

    [ INFO: possible recursive locking detected ]
    multiload-apple/2820 is trying to acquire lock:
    (af_callback_keys + sk->sk_family#3){-.-?}, at: [<c119d8db>]

    but task is already holding lock:
    (af_callback_keys + sk->sk_family#3){-.-?}, at: [<c119d8db>]

    other info that might help us debug this:
    3 locks held by multiload-apple/2820:
