Just posted this to the bug tracker:
https://sourceforge.net/tracker/?func=detail&aid=3043936&group_id=42302&atid=447449

---------------8<-snip--------------------------------

Problem: After a while (few minutes mostly) NIC is not receiving any data.

Affected NIC: Device ID 10ef rev 06.

Seen on various distribution (RHEL 5.5, openSUSE 11.3).

Details:
I have several mainboards with IbexPeak chipset and this LAN chip.
Mainboards with LAN chip rev 05 work without problem with the
distributions mentioned above, mainboards with a LAN chip rev 06 are
causing problems:
- Installation over PXE stops after a while and complains about not
avaialble packages (in fact there is no connection the the Install
server any more)
- Transfers on a running system stop after a while

I traced this with wireshark on a system that show the error. If I ping
to anohter station I see that the system that shows the error is still
sending out ARP packet, but doesn't respond tot the ARP responses. The
other way round, if I want to ping the system from outside, the
initiator is sending out ARP packets that are never answered. So it
looks like that receiving from the LAN is dead when the error occurs.

As mentioned above this failure is only seen on boards with LAN chip rev
06. So the question is: What is different between rev 05 and rev 06
chips and do we need to address this in the driver (would be bad since
all distors ship with the old drivers) or is this a firmware issue?

Sorry to bother you both on the bug tracker and the mailing list with
this, but I guess its urgent since my company is shipping systems with
the rev 06 chip every day.

Rainer
