Kernel panics while booting linux if mellanox card is connected to the network. It boots okay if I disconnect the card.
(after it successfully boots I can connect it to the network. though it sometime(not always) causes host to hang when I run ping over the network, for which I don't have much details to post..)
Here are details on the system
