network card problems

[Gabriel J. Weinstock]

One of my co-workers is having a problem with his CNet SinglePoint 10/100 
CardBus PC card on his laptop, and I thought I would ask the gurus here since 
so many of you have done kernel/network driver development.

Essentially, what is happening is that the driver is dumping huge amount of 
messages to the syslog facility, to the point of filling up his root 
partition. The messages are as follows:
-----
kernel: rtl8139_rx_interrupt: eth0: In rtl8139_rx(), current ef74 BufAddr 
efd8, free to ef64, Cmd 0c.
kernel: rtl8139_rx_interrupt: eth0:  rtl8139_rx() status 602001, size 0060, 
cur ef74.
kernel: rtl8139_rx_interrupt: eth0: Done rtl8139_rx(), current efd8 BufAddr 
efd8, free to efc8, Cmd 0d.
kernel: rtl8139_interrupt: eth0: interrupt status=0x0000 ackstat=0x0000 new 
intstat=0x0000.
kernel: rtl8139_interrupt: eth0: exiting interrupt, intr_status=0x0000.
kernel: rtl8139_interrupt: eth0: interrupt status=0x0000 ackstat=0x0001 new 
intstat=0x0001.

I have no clue as to why this is happening and what to do about it.
If anyone has any suggestions, I would greatly appreciate it.
Thanks,
Gabriel
