This is a KERN_DEBUG advisory message indicating you ran out of transmit descriptors. This can happen under heavy load. In current mainline this message is filtered by netif_msg_tx_queued, and by default the message will not be issued; it can be turned on using ethtool -s ethX msglvl <value>.

and
atl1 0000:01:00.0: hw csum wrong, pkt_flag:1600, err_flag:80
This is also a KERN_DEBUG message, and it indicates that a received packet was too short.
pkt_flag:1600 - ipv4, tcp, packet with error
err_flag:80 - runt packet
In current mainline this message is filtered by netif_msg_rx_err, so it too can be controlled with ethtool (and will also be off by default).
To get rid of the messages in your 2.6.24 kernel, you might try reducing the loglevel to exclude KERN_DEBUG messages.
