Broadcom BCM5906M ethernet adapter (tg3) hangs under heavy tcp load (bittorrent) when generic segmentation offload (gso) is in use

When intense concurrent TCP traffic occurs (I use bittorrent for testing), the network adapter just hangs after a few seconds (no longer receives any ethernet packets).

“ip link set eth0 down” followed by “ip link set eth0 up” corrects the situation. However, after a few seconds of bittorrent traffic, the adapter hangs again. The total traffic (in+out) was below 2 MiB/s when this occured.

The problem does not occur when instead of bittorrent traffic a single “high” data rate TCP stream is used (7 MiB/s inbound).

After deactivating generic receive offload via “sudo ethtool -K eth0 gso off”, the problem does not occur with any traffic pattern I tried.

On an older kernel version I apparently waited long enough for the kernel to notice and correct the problem, I found this in an old kernel message log:

[Marc D. (koshy)]

The problem still exists in

ii linux-image-generic 2.6.31.14.27 Generic Linux kernel image

gso is on by default so this should be fixed, switching off gso on affected hardware would be enough.

I now had the time to test whether the driver recovers automatically, and indeed it does, as the attached log shows.

The problem still exists in

ii linux-image-generic 2.6.31.14.27 Generic Linux kernel image

…and I just discovered that it is even worse than previously thought. The bug introduces silent data corruption.

I was just trying to update my backup (this time over Ethernet instead of WLAN, because I added a lot of data) but it never remotely finished because SSH noticed a data corruption in the network transmission:

debug1: Sending command: rsync --server --sender -vlHogDtprSe.iLs --numeric-ids . /mnt/image/
receiving incremental file list
Disconnecting: Corrupted MAC on input.
rsync: connection unexpectedly closed (55356 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [receiver=3.0.6]
rsync: writefd_unbuffered failed to write 5 bytes to socket [generator]: Broken pipe (32)
rsync error: unexplained error (code 255) at io.c(1525) [generator=3.0.6]

Of course, the problem disappeared after I deactivated gso.

[deseven (de7)]

I have Lenovo S10 and the same problem with ubuntu kernel 2.6.31-15.
Same symptoms, same logs, same solution (ethtool -K eth0 gso off).

[Michał Markowski (markowski)]

I have HP 6715s with this ethernet adapter and "ethtool -K eth0 gso off" solve this problem.
Kernel: 2.6.31-15

[Jeremy Foshee (jeremyfoshee)]

Hi Marc,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 404708

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Marc D. (koshy)]

I no longer have access to that piece of hardware. I am going to test with an upstream kernel when I get that opportunity.

[eitch (eitch)]

I have a similar problem. I can't even run aptitude update without the driver failing.

If I switch off rx and tx with ethtool, then the everything works flawlessly, even with heavy loads.

I didn't use to have this problem with Jaunty.

[Marcel (ubuntu-no-network)]

Just found this one and marked my bug #544390 as a duplicate.

Deactivated gso works for me, also setting the MTU from 1500 to e.g. 1000 works, so I suspect the module only corrupts data packages that are large enough.

I can reproduce this bug on karmic and also on the current lucid beta, both running on a Lenovo S10e with the mentioned network chip.

[Vegar (vneshaug)]

I can confirm this bug on a Lenovo Ideapad S9E(NIC BCM5906M). The problem was noticed for the first time when using the Ideapad as a pulseaudio network sound server. Turning off gso alone did not solve the problem for all traffic patterns. Setting the MTU to 1000 AND turning off gso solved the problem for all tested traffic patterns.

Thanks for posting a solution!

mainline/v2.6.34-rc2-karmic/linux-image-2.6.34-020634rc2-generic_2.6.34-020634rc2_i386.deb

crashes less than one second into the boot.

In

mainline/v2.6.32.9/linux-image-2.6.32-02063209-generic_2.6.32-02063209_i386.deb

the problem still exists.

In

mainline/v2.6.33/linux-image-2.6.33-020633-generic_2.6.33-020633_i386.deb

the problem is gone (transferred several Gigabytes with SSH without a MAC error), however, I cannot use that kernel because wl.ko for the WLAN interface Broadcom BCM4312 fails to build for it.

[Marc D. (koshy)]

I forgot: in mainline/v2.6.33/linux-image-2.6.33-020633-generic_2.6.33-020633_i386.deb, gso is switched *on* but the problem is gone.

Can anyone else please confirm this?

Also, after today, I will no longer have access to the affected hardware (sold), so I will mark myself unaffected by this bug. Would someone else please cooperate with the maintainer so that a fixed Kernel lands in Ubuntu?

[Marcel (ubuntu-no-network)]

> Can anyone else please confirm this?

For 2.6.32-9 mainline, I can confirm the problem still exists, same error as on the karmic standard installation.

For 2.6.33 mainline, the network does not produce corrupted data any more (with gso on and mtu unchanged at 1500), but -at least on my machine- the performance becomes very poor (about 2.5 MB/s). Switching gso off or changing the MTU down to 1000 brings performance back to over 10 MB/s.

> Would someone else please cooperate with the maintainer so that a fixed Kernel lands in Ubuntu?

I have access to one or two S10e netbooks with that network chip if any more testing is needed.

[ambient_sky (devicebusy)]

Same problem on Lenovo 3000 N200, on generic kernel and 2.6.33-zen2, i have try also last stable transmission (1.92) but same result.
