The following messages are usually caused by an Intel Ethernet Express Pro 100 card sharing an IRQ with other devices:

eth0: card reports no RX buffers.
eth0: card reports no resources.

If you have one of these cards and this problem exists you will need to go through the BIOS to force this card to use a unique IRQ.

If you have two of these cards installed and this problem exists try replacing one of the cards with another NIC (check our compatibility list.) If this does not work make sure that this card is using unique IRQ through your BIOS. For more assistance, refer to the manual included with the network card, or to the manufacturer's website.
