Ethernet not working! (forcedeth)

[sazo]

Hi!

I use archlinux and gentoo linux. I used to use wireless, but now I have the possibility to use cable.

But for some reason I can't get it to work, not in arch, gentoo, knoppix (livecd) or ubuntu (livecd).

It always times out when trying to get an IP... And on dmesg I always get the same "forcedeth: eth0: no link during initialization" error.. :-(

ethtool

You have a dhcp server on a router?

Or give yourself a static IP?

[sazo]

yes I have a dhcp server on the router. which is running fine on every machine, including this one if i switch to wireless.

I tried using static ip but the problem is exactly the same.

here is my lspci output:

The lspci shows no ethernet controller
Is it disabled in bios settings? Is it working in Windows perhaps?

Yes it's enabled in BIOS settings, and works like a charm in Vista... although I prefer using my other linux box to using windows.. :thumbdwn:

[CptDondo]

I've been fighting this for a while. There is something really badly broken with the MCP55 ethernet + linux. For some reason the PHY gets disabled, and then there's hell to pay trying to get it back.

See for example http://www.gossamer-threads.com/lists/linux/kernel/1046277

If you google around, you'll find lots of people with this problem.

I have several of the Asus M2N-SLI Deluxe boards; they're absolutely stable under load except for this ethernet issue. I have not found a reliable way to re-enable the NIC once the PHY is shut down.

It's a software issue but how does one force a reset?

[CptDondo]

HAH! Progress of sorts.

http://patchwork.kernel.org/patch/16212/

So now i can turn on and off the links.

ethtool -s eth1 autoneg off speed 10 duplex full

turns on the link, and gets me half-duplex, 10mb/sec. Not much, granted.

ethtool -s eth0 autoneg off speed 100 duplex full

causes the link to go up and down on about a 2 second cycle.

ethtool -s eth1 autoneg on

causes the link to drop.

So the problem is in the autoneg code. It's a driver issue. I've tried the patch; no joy but I have yet to reboot the system.

[CptDondo]

I've been reading the forcedeth.c code.

So far I've established that it does recognize the Marvell PHY. AFAIK, the PHY on the board is 88E1116, so that much is right. OK, not much progress.

In nv_probe, there are some lines that should turn on the PHY. I stuck some printk in there to see what's happening. Turns out nothing is happening..... powerstate remains 0? Does this mean that the power is already on? Or that we're reading/writing the wrong register?

if (id->driver_data & DEV_HAS_POWER_CNTRL) {

/* take phy and nic out of low power mode */
powerstate = readl(base + NvRegPowerState2);
printk(KERN_INFO "Turning on power: 0x%04x.\n",powerstate);
powerstate &= ~NVREG_POWERSTATE2_POWERUP_MASK;
if ((id->device == PCI_DEVICE_ID_NVIDIA_NVENET_12 ||
id->device == PCI_DEVICE_ID_NVIDIA_NVENET_13) &&
pci_dev->revision >= 0xA3)
powerstate |= NVREG_POWERSTATE2_POWERUP_REV_A3;
printk(KERN_INFO "Writing powerstate: 0x%04x.\n",powerstate);
writel(powerstate, base + NvRegPowerState2);
powerstate = readl(base + NvRegPowerState2);
printk(KERN_INFO "Powerstate 0x%04x.\n",powerstate);
}

(this is getting more urgent; I rebooted the machine and lost both network ports. Instead of dual-gigabit I'm running off an ancient PCI card. I'm willing to test/build/debug, but I need some input from those who understand the forcedeth code....)

[dkjkj]

Just to add on OpenSuse 11.0 I have a problem what the link starts flapping at random times. It has noting to do with the connection. Have tried to change port on switch.
Hardware Supermicro server nVidia MCP55 bridge rev a3. Forcedeth ver 0.61 from Open Suse.

[Harri]

I got the same problem (no link at init) on a shiny new Acer Revo (i.e. the Ion platform). Sometimes it gets a link, but usually it doesn't. Too bad.

options forcedeth optimization_mode=2 msi=1 dma_64bit=1 phy_power_down=0



I have a DHCP server running for the home LAN here, and as of kernel release 2.6.29 there were some changes to the forcedeth driver code, which powered down the NIC during reboots/power off. It caused havoc for many, because the NIC did not power up at next boot.
I couldn't get an IP address without repeatedly restarting the network a bunch of times, and never got an IP during boot, it just hung.

The driver regression was reverted in 2.6.29.3 or .4 but still the default behavior seemed to be to remain powered off.

What I posted above is from my 'forcedeth' file in /etc/modprobe.d folder.
Notice the option "phy_power_down" option! It makes the NIC stay powered up during reboots etc.. Voila! Now it works perfect again, getting its IP from DHCP in a blink of an eye during boot.

You can use either the 'modinfo' command, or look at the bottom of the forcedeth.c sourcecode, for all the parameters you can pass to the driver.

Good luck; hope this helps.

options forcedeth optimization_mode=2



Hi,

what means optimization_mode=2 ?

I've looked to the sources (2.6.18, 2.6.24, 2.6.29) and found next:

/*
* Optimization can be either throuput mode or cpu mode
*
* Throughput Mode: Every tx and rx packet will generate an interrupt.
* CPU Mode: Interrupts are controlled by a timer.
*/
static int optimization_mode = NV_OPTIMIZATION_MODE_THROUGHPUT;

module_param(optimization_mode, int, 0);
MODULE_PARM_DESC(optimization_mode, "In throughput mode (0), every tx & rx packet will generate an interrupt. In CPU mode (1), interrupts are controlled by a timer.");


i.e by default optimization_mode is "0" (throughput mode), and possible change to "1" (CPU mode)

[vish_acer_revo]

So did anyone workout how to get the wire lan working on on the acer revo running ubuntu? I've got the same problem, network card has no link but the wireless card works fine.

[Harri]

I would recommend to give Sasha's config file a try.

Another option would be to upgrade to kernel 2.6.30.4. Works fine for me.
