Steps to reproduce:

boot kernel
Comment 1 Alexey Dobriyan 2008-09-08 21:23:48 UTC 
Not suprisingly:

        /* Init GPHY as early as possible due to power saving issue  */
        spin_lock(&adapter->mdio_lock);
        atl1e_phy_init(&adapter->hw);
        spin_unlock(&adapter->mdio_lock);

atl1e_phy_init() does msleep()
