/etc/organization
>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.

 Hi -
 
 I also have the problem at times.
 I guess that kern/4270 and kern/5347 are caused by the same bug.
 
 I had the bug on 2.2.6  with a 3Com 509 card (ep0 driver). I changed ALL the
 hardware (not the HUP though, just moved to another port.) and upgraded to
 3.1, using a 3Com 905 (xl0 driver)  card.
 
 But problem remains...
 
 On 2.2.6 I could do a ifconfig up to clear up the problem, but 3.1 crashes!

 There have been some reports on Usenet that the "D" version of
 the 3c589 is a problem child.
 
 I've got a Compaq Armanda 7800 with one of these cards, I purchased
 a 3c589 "C" version off of Ebay for about $25 I think it was.  I've not
 seen this problem.
 
 It might be worth experimenting - "B" and "C" versions of this
 PC card regularly come up for very little money on Ebay - I just
 did a search on this today (1/12/2000) and there were 9 of the
 cards listed - all for under $15 per card.

 This PR should be closed - it's the same bug as on PR  kern/8861
 
 I've posted more info there as well.
