My system is a fc1 system (yeah I know... :( ):
[r...@xxx root]# uname -a
Linux xxx 2.4.22-1.2174.nptlsmp #1 SMP Wed Feb 18 16:21:50 EST 2004
i686 i686 i386 GNU/Linux
running a pretty old (5.2.16) version of the e1000 driver:
[r...@xxx root]# ethtool -i eth0
driver: e1000
version: 5.2.16
firmware-version: N/A
bus-info: 01:01.0
I am seeing the eth0 device "flapping" (transitioning frequently from
link up to link down and back ala:
Apr 2 12:03:35 delivery kernel: e1000: eth0 NIC Link is Down
Apr 2 12:03:37 delivery kernel: e1000: eth0 NIC Link is Up 1000 Mbps
Full Duplex
Apr 2 12:03:39 delivery kernel: e1000: eth0 NIC Link is Down
Apr 2 12:03:42 delivery kernel: e1000: eth0 NIC Link is Up 1000 Mbps
Full Duplex
[...]
Ethtool shows our end in auto-negotiation mode and supposedly thw
switch is set teh same way:
[r...@xxx root]# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full

1000baseT/Full

I ran a ethtool diag test and got a FAIL result with the loopback test
showing a result of 13.
[r...@delivery root]# ethtool -t eth0 offline
The test result is FAIL
The test extra info:
Register test (offline) 0
Eeprom test (offline) 0
Interrupt test (offline) 0
Loopback test (offline) 13
Link test (on/offline) 0
Curious as to what the 13 is telling me? Can someone also give me a
clue as to where in the current e1000 source code I should be looking
to see how self-test is done and if these result codes are documented
there in any way. (You know like "teach a man to fish...").
Thanks!
Chris
