>Environment:

FreeBSD 3.0-CURRENT OS, sup'ed last friday, and installed with make world.
The system is a DeLL Latitude laptop.
The ethernet card is a PCMCIA card, 3COM etherlink III, type 3C589D-COMBO
I use the ep0 driver, and the PCMCIA support.

>Description:

While trying to backup the laptop using amanda over the network, the ep0
driver suddenly stops working and any attempt to send traffic over the
network fails.

If I try to backup over the network, while in another window I run a ping
then suddenly, the ping stops responding and the message "no buffer space
available" is printed. 

Simply doing ifconfig ep0 down ; ifconfig ep0 up solves the probem and the
ping continues. Unfortunately, by that time the amanda backup has already
been aborted.

I think the problem is due to heavy network load, but I have no evidence
to support this.

The problem is reproducable using amanda (I tried three times).

Let me know, if you need more information.
