I came across this message because I was searching for something having "FIFO diagnostic register 2000" in it. I get this error from my 3c574TX PCMCIA card on my Olivetti Echos P90M. It seems to happen when I have heavy downloading from the Internet, or the card has to send large amounts of data for network backups of my laptop through amanda. It starts saying "FIFO diagnostic register 2000", then "Interrupts dropped" a lot of times. I use pcmcia-3.0.13-10. Is my card defective too?
