Linux network driver bug?

Hello all, I have CentOS linux installed and using a PCMCIA Melco LPC3-TX card. Once in a while (especially very long idle time with apache, mysql or some other network service running) the shell prompt display an error:
BUG: warning at drivers/net/pcmcia/axnet_cs.c:1586/ei_rx_overrun() (Not tainted)


What does this mean in terms of my network card or driver? I'm using the driver that comes with kernel 2.6, should I find a more updated driver?

I'm not sure if this is the shell prompt or just the console displaying a log message in your shell prompt window. This can be a problem if your display is a system console device.

Assuming that everything's running OK, you can probably safely ignore this. But it probably wouldn't hurt to have YUM do a check-update and see if there's a newer kernel (including drivers).

Thanks Tim for your input. What do you mean if my display is a system console device? I don't have GUI or XWindows on my Linux box. So I don't think the display has anything to do with the message.

That explains it then. Your console is the monitor display. So in addition to getting the user login-related stuff, it's also where terminal-destinated system messages display. Sometimes rather rudely, since it doesn't bother to check what you're doing in the login session when it pops out a log message.

I see. So do I need to do anything to my display driver or something to prevent or suppress the message?
