[ewg] [Fwd: Re: [ofa-general] Problem with latest OFED 1.3 build... IPoIB and iPATH]

Hello Ralph,

What's ifconfig ib0 output?

int ipoib_ib_dev_open(struct net_device *dev)
{
        struct ipoib_dev_priv *priv = netdev_priv(dev);
        int ret;

        if (ib_find_pkey(priv->ca, priv->port, priv->pkey,
&priv->pkey_index)) {
                ipoib_warn(priv, "P_Key 0x%04x not found\n",
priv->pkey);
                clear_bit(IPOIB_PKEY_ASSIGNED, &priv->flags);
                return -1;
        }
        set_bit(IPOIB_PKEY_ASSIGNED, &priv->flags);

        ret = create_own_ah(priv);
        if (ret) {
                priv->own_ah = NULL;
                ipoib_warn(priv, "failed to create own ah\n");
                return -1;
        }

Looks like the ipath driver returns error from create_own_ah() call. Are
you sure there is no ipath driver changes between RC3 and RC4?

Which kernel did you hit this problem? What's the kernel PAGE_SIZE?

thanks
Shirley
