So I have 3 of these motherboards and I havent had problems with the ethernet until recently.

I moved over the weekend and some how in the move the ethernet stopped negotiating to 1000mbits

here is the lspci

and the ethtool

Code: 
Settings for eth0:

	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full

	Port: MII
	PHYAD: 3
	Transceiver: external

	Link detected: yes

as you can see the problem is obviously in the advertising. I tried to use ethtool to force the speed but I got an invalid command.

Running Mythbuntu 9.04 with the 2.6.26-15-server kernel. I also tried a Linux Mint 7 64 bit live cd, which accepts the exact same ethtool command and from the lights you can tell that it takes the network down and brings it back up but it still only broadcasts at 100mbits.

I'm at a loss here. I haven't done any updates since the time I took the server down on Friday to the time I brought it back up on saturday.:screwy::screwy::bang head:bang head:bang head

Any help would be appreciated.

p.s. I swapped the cables 5 times now. I am 100% sure its not the cables.
 
Please post: dmesg | grep -i -C 10 eth

I want to see what driver it is using, as well as anything else the kernel was thinking...

I have actually seen drivers used for 100baseT instead on 1000baseT adapters when the hardware supports 1000 but is compatible with the older driver.

Did you build your own kernel, or do you have every driver in the world available?
 
Have you checked outside of the machine, to make sure that the switch is set correctly and advertising 1000mbps? Plug another machine into that same cable and see what you get. I wouldn't be surprised to see that the switch is the issue.

its using the forcedeth driver, I will post the dmesg momentarily
no I didn't compile my own kernel, I am using hte server kernel available in the repos

Regarding the switch, would that change what the ethernet card is actually advertising? If you notice the card is only advertising at 100 mbit speeds for whatever reason... So if the switch was faulty, it just wouldnt negotiate at gigabit speeds but it still should advertise as such


EDIT: confirmed it is not the switch, a different computer negotiates at gigabit on the same switch with the same cord

EDIT2: booted the default kernel with no change in luck. In fact now I cant even get it to connect to the network because the clocksource tsc is unstable

EDIT3: fixed the timing issue, couldnt connect still, plugged in wireless card to retrieve MRD's requested info

Finally got it to negotiate at gigabit speeds, I turned off the autoneg and then turned it back on again and set the speed to 1000, light went green, still cant pull an ip from the dhcp server though

I get the following (abreviated because there are a lot of attempts)

Code: 
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 5
No DHCPOFFERS received
No working leases in persistent database - sleeping

now obviously, the router is functioning fine as I wouldnt be able to type this to you now. I have tried 3 computers, only 1 has problems. All 3 have onboard nics and wireless cards. All 3 wireless cards authenticate and get leases. Only 1 of them has this problem. I have went back kernel versions, went to liveCDs etc.

All I can say is I think its the onboard network card that has apparently died on me?

That dmesg does not look right... What do you mean when you say that it was done with the wireless card?

For example, I get:

Code: 
dmesg | grep -i eth
eth0: Tigon3 [partno(AC91001A1) rev 0105] (PCI:33MHz:32-bit)
eth0: attached PHY is 5701 (10/100/1000Base-T Ethernet) (WireSpeed[1])
eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[0]
eth0: dma_rwctrl[76ff000f] dma_mask[64-bit]
ADDRCONF(NETDEV_UP): eth0: link is not ready
tg3: eth0: Link is up at 1000 Mbps, full duplex.
tg3: eth0: Flow control is on for TX and on for RX.
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present

You should see something more like this... It should be seeing the ethernet adapter and telling you what speed it is bringing it up at.

Try it with the wireless card out... even if it only uses 100, I want to see the output of dmesg w/o any wireless card installed.

Click to expand...

I mean in or to get the output (to copy it and paste into the terminal i needed to plug in the wireless card because the nic is no longer accepting leases from the DHCP for some strange reason. Also I copied it exactly so the "-C 10" was included in the output if you want me to grep for only eth I can do that.

found my own answer here

The onboard nForce4 Gigabit port sometimes stop working. In the system log file (/var/log/message), the kernel reports the following error messages:

Jan 1 10:58:28 manet kernel: NETDEV WATCHDOG: eth0: transmit timed out
Jan 1 10:58:28 manet kernel: nv_stop_tx: TransmitterStatus remained busy<7>eth0:
tx_timeout: dead entries!

To restore the network connection, the system has to be shut down and the power cord has to be disconnected temporary. Powering off the system only does not bring back the network.
Click to expand...

Doing this and then manually calling the dhclient for eth0 allows me to connect. Now all I have to do is figure out why network manager refuses to manage this connection...
 
Well i was able to fix the remaining problems.

I purged the system of the network manager, called the dhclient to make sure nothing had changed, then reinstalled the network manager and rebooted. It now finds all of my devices.

What a weird bug
