Description glshank 2003-04-10 21:17:07 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.2) Gecko/20030208

Description of problem:
After upgrading to AS 2.1 from RH 7.1, my Intel GB NIC is no longer working. It
is properly configured and up:

# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:03:47:4E:31:DE  
          inet addr:  Bcast:  Mask:
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:23 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:0 (0.0 b)  TX bytes:1472 (1.4 Kb)
          Interrupt:19 Memory:f9ae0000-f9b00000

But trying to ping the host at the other end of the fibre cable returns:

# ping
PING ( from : 56(84) bytes of data.
From Destination Host Unreachable

I've tried the stock e1000.o driver and the e1000_4412k1.o driver to no avail.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Install Intel PRO/1000 GB NIC (FIBRE, not twisted pair)
2.Connect a cross-over fibre cable to a GB NIC on another host
3.Configure NIC and try to ping other host

Actual Results:  # ping
PING ( from : 56(84) bytes of data.
From Destination Host Unreachable

Expected Results:  # ping
PING ( from : 56(84) bytes of data.
64 bytes from icmp_seq=0 ttl=255 time=28 usec
64 bytes from icmp_seq=1 ttl=255 time=13 usec

Additional info:

This is a DELL Poweredge server running all the latest errata from rhn.

I was working with the customer on the support line.

PCI:ID is 8086:1001 (rev 2)

Either the card does not contain an inernal xcvr, or the driver/hardware is
ignoring ethtool requests to use the internal xcvr.

We have tried the 2.4.9-e.18smp QU2 beta errata kernel with the e1000 (version
5.0.43-k1) driver and the problem still occurs. The card worked fine under Red
Hat 7.1 using kernel 2.4.9-31.

Just for grins, we rebooted the box at the other end of this fibre cable. It is
working now. I apologize for wasting your time with this apparent red herring.
