2nd NIC is off on Asus M2N-SLI Deluxe (nForce 570 SLI MCP)

[extensive2]

Hello,
I have a problem with the second of my two on-board NICs on the Asus M2N-SLI Deluxe (chipset: nForce 750 SLI MCP): It is completely dead after booting Linux.

To reproduce the problem:
1) Power supply off.
2) Power supply on: both NICs get GBit link (LEDs are on).
3) System power on, waiting for GRUB to load: both NICs still have link.
4) Booting kernel: upon loading of forcedeth, both NICs get turned off (LEDs off).
5) somewhat later in the boot sequence: first NIC gets link again, but second link never comes up

This could be reproduced with forcedeth versions 0.56, 0.59 and 0.60, in kernels 2.6.18, 2.6.20 and 2.6.21-rc6 (all amd64). The processor is an Athlon64 X2 5000+. I tried Asus BIOS versions 0404 and 0903.

On some very rare occasions albeit, the second NIC "just worked". Once after cold boot and another time (surprisingly) after unplugging and replugging the network cable. (This was luck. Switching cables between the NICs does not help, usually, the problem stays with the 2nd NIC.)

Maybe another interesting point: when doing
6) reboot: the 2nd NIC stays off, even during initialisation of BIOS
Cold power off is necessary to get the 2nd NIC to work during BIOS initialisation.

[chunkey]

your dmesg & ethtool info is a bit out of sync... (or do you remap the eths?)

dmesg:
eth0: forcedeth.c: subsystem: 01043:8239 bound to 0000:00:08.0
eth1: forcedeth.c: subsystem: 01043:8239 bound to 0000:00:09.0
eth2: (3Com PCI 3c905B Cyclone 100baseTx at ffffc20000026000.)

ethtool:
# ethtool -i eth2
driver: forcedeth
...
# ethtool -i eth1
driver: forcedeth

Anyway, I think you should talk to the forcedeth maintainer... he probably knows what's going on, or has atleast some ideas what ASUS screwed up...

[extensive2]

Indeed, it is remapped by udev:


# cat /etc/udev/rules.d/z25_persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, probably run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.

I added the Intel card as a replacement for the faulty on-board NIC, the problem shows without this card, too. Yet, I can't remember whether I ever tested without the 3com card. Tomorrow I will test again, with both additional network cards removed.

Maintainer: You mean Manfred Spraul? I found his name in forcedeth.c, but he is not listed in MAINTAINERS.

[netllama]

Do these options have any impact?
"options forcedeth msi=0 msix=0"

[extensive2]

I removed the two other NICs, so that there is no remapping being done anymore. Now the system looks like that:

And I put msi=0 msix=0 in /etc/initramfs-tools/modules ...

# cat /etc/initramfs-tools/modules

#
# Syntax: module_name [args ...]

forcedeth msi=0 msix=0
rr2340

... which however did not improve the situation.

I got lucky once after a cold boot (out of approx. ten tries), to have both NICs working. I'm attaching dmesg output of the occasion when both NICs worked and the same for a "normal" occurence, when only the first NIC was working. Both contain full forcedeth debug output, so maybe (hopefully) that will be sufficient to figure out what is going on.

[chunkey]

ahh, a lspci -v , /proc/interrupts, ... would have been nice.

ahh, a lspci -v , /proc/interrupts, ... would have been nice.

I re-added the intel NIC as eth2. Forcedeth is eth0 and eth1.

Anything else you'd be interested in?

[netllama]

You stated that you "put msi=0 msix=0 in /etc/initramfs-tools/modules". Is that traditionally where your Linux distribution keeps its kernel module options, rather than modprobe.conf? Did you rebuild the initrd & reboot after making that change?

If you boot with hpet=disable does that have any impact?

You stated that you "put msi=0 msix=0 in /etc/initramfs-tools/modules". Is that traditionally where your Linux distribution keeps its kernel module options, rather than modprobe.conf?
I was not sure whether modprobe.conf would be honoured by modules loaded from initrd, that's why I put it in /etc/initramfs-tools/modules. (I'm using Debian Etch (amd64) by the way.) Of course I also tried to modprobe forcedeth msi=0 msix=0 on the command line, but it was all to no avail.
Did you rebuild the initrd & reboot after making that change?
Yes.
If you boot with hpet=disable does that have any impact?
No, I don't see any change.

I originally posted a detailed replay, but much to my dismay, these forums appear to wipe your post if you aren't logged in when you hit quick reply so I lost it ;( Between that and the captcha on the registration page being quite possibly the worst I have ever seen...doh. But I digress, I'll give you the brief version of my now lost post.

I just built 4 machines using this mobo on 32 bit etch 2.6.21 smp (64x2 6000+). 2 machines are fine, both interfaces work as expected. On the other 2 machines, port 1 is fine and port 2 is bad. One of them is identical to the problems experienced by Extensive2, including the workaround. On the other, the 2nd nic comes up, but errors on about 5 of every 6 frames it processes. I get a throughput of around 2-4k/s on it. Using either of the good machines over the same infrastructrue works as expected. I haven't tried the msi=0, msix=0 parameters yet, I will do that now and post my experience.

Thanks for taking the time to repost!

To me that seems to indicate a production error at Asus. Maybe we should just return the erroneous boards. What's your opinion?

Same issue here :thumbdwn:

I bought a new NIC, but I'm upset that this may indicate other issues on the board.

Let me know what you guys do.

Essentially, I did the same. I added an Intel dual-GLAN PCIe network adapter, which is working fine.
I should have returned the board to the retailer (especially with the evidence gathered in this thread so far), but I already had integrated it into a production system and didn't want to take it down again.
