(net 8139too) system with two of these ethernet cards, under any reasonable load, generates NETDEV WATCHDOG: eth0: transmit timed out

[Bradley M. Kuhn]

Binary package hint: linux-image-2.6.24-16-generic

I have also submitted an upstream bug on a later version of the kernel,
which generates the exact same bug:
      http://bugzilla.kernel.org/show_bug.cgi?id=10682

I have an eBox-4852 which has two of these ethernet cards in it:
     Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10

As soon as I get both ethernet cards up and running and put any reasonable
load (using the system as a packet-forwarding firewall), one or both of
them fail for a number of minutes. Eventually, they usually come back up
on their own, at which time the following message appears in the syslog:

kernel: [ 558.122829] NETDEV WATCHDOG: eth0: transmit timed out
kernel: [ 561.120915] eth0: Transmit timeout, status 0d 0000 c07f media 10.

kernel: [ 561.121000] eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

They are both recognized at boot time to use the 8139too module:

kernel: [ 19.550923] ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 10

It's very simple, one needs only to have this box and run both cards with
any amount of reasonable load and it occurs within an hour, usually much
faster. I read online that sometimes WATCHDOG TIMEOUT means that there is
bad network infrastructure of some sort. I have tried many different
network topologies, hubs, and cables and it always produces the same
error. I have also tried all different possible BIOS settings related to
IRQs.

Based on advice from online forums and the like, I have also tried the
following kernel command line settings, in sequence and together in
various ways, and the behavior is still the same:

nosmp
irqpoll
pci=biosirq
pci=irqmasq
pci=routeirq

I have also recompiled the kernel, messing with these various settings to
no impact:

8139_OLD_RX_RESET
8139TOO_8129
8139TOO_TUNE_TWISTER
8139TOO_PIO

In particular, I have the same behavior with the old and new RX reset settings
and I've tried both MMIO and PIO.

Here is all the data from the running system related to the kernel:

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[IKT (ikt)]

I have a MSI motherboard also with Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ network adapter, my problem is that it just plain doesn't work, tested with 8.04 and 8.10 alpha 6.

Motherboard is MSI MS-7267

[kernel-janitor (kernel-janitor)]

Hi bkuhn-ebb,

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-image-`uname -r` 229392

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.]

[Ixhausen (harneit)]

I think I am seeing a related behavior on my machine, and started to query the kubuntu forums on network support
( http://kubuntuforums.net/forums/index.php?topic=3105955.0 ), but maybe it's better placed here.

If you guide me a little bit (linux newbie, but computer-experienced), I'm willing to provide all information I can possibly
retrieve from the system. Note that I have no network access from kubuntu, so I cannot install packages on the fly.

SYSTEM HARDWARE
+ motherboard: MSI-7222 (VIA chipset), 2GB RAM installed (1GB recognized by Phoenix BIOS, seems a known bug)
+ ethernet adapter: RealTek RTL8139/810x Family Fast Ethernet NIC (as per windows), running fine in winXP.
+ graphics adapter: ATI Radeon HD 3450 (AGP 8x)
+ no other PCI devices

SYSTEM SOFTWARE
+ WinXP running on one partition (with network access through dsl cable router), dual-boot system
+ Installed kubuntu 9.04 from iso image (-i386 live CD), downloaded 3 days ago. "Ubuntu 9.04, kernel 2.6.28-11-generic"
+ Removed network-manager-kde, trafficked /etc/network/interfaces, following advice in various forums
+ nothing else installed, since no network access

SYMPTOMS
+ no network access through wired connection to cable router
+ various configurations in /etc/network/interfaces (dhcp, static) gave no result
+ trying to add router manually via route add ... was impossible [SIOADDRT: no such device]

VAR/LOG/SYSLOG
+ shows I'm running realtek8139too
+ shows WATCHDOG NETDEV warning and trace
+ is attached (I can access winXP boot partition from kubuntu and save files there for uploading)

APPORT-COLLECT
+ failed with the message Please install the package "python-launchpadlib".

So, if there is anyone out there willing to tackle this problem together with me, I'm game...

[Ixhausen (harneit)]

OK, successfully downloaded and installed "upstream kernel" 2.6.31-999-generic.

NETDEV WATCHDOG is my best friend:
Aug 24 00:54:35 crunchy kernel: [ 20.826016] WARNING: at /home/kernel-ppa/mainline/build/net/sched/sch_generic.c:246 dev_watchdog+0x238/0x250()

added delight: the X server crashed now, too.
Aug 24 00:54:50 crunchy kdm[2900]: X server for display :0 terminated unexpectedly

Since I now use the excellent Ext2Fsd package on winXP to access the linux ext3 partitions, I can even attach the new syslog without rebooting twice.

I changed (removed) the "needs-upstream-testing" tag, as described.
I also removed the "need-kernel-logs" tag, since mine is attached with this message (or do you need anything else?)
Maybe the status of this bug should be changed altogether to "confirmed", huh?

[Ixhausen (harneit)]

Aaaah! I heff ze internet now!

The (trivial!) solution to the single-ethernet-adapter branch of the bug above was actually in

http://ubuntuforums.org/showthread.php?t=538448

Briefly, my RealTek adapter was just put to sleep by Windows on shutdown, and kubuntu could not re-awaken it (even in kernel 2.6.31-999).

I simply followed the advice given at the link above and told WinXP to leave the RealTek on (by starting the device manager, locating the RealTek adapter there, dbl-clicking it, and applying the following setting in the advanced tab: Wake-On-Lan After Shutdown = Enabled).

This behavior may be more general than I thought before. Lots of new *ubuntu users complain about very bad network support, which is of course a show-stopper for the transitionally-minded.

Maybe the Wake-On-Lan feature is now ubiquitous in the ethernet adapter world?

I guess that many newbies actually start off with a dual-boot installation, or just try the liveCD RIGHT AFTER WINDOWS SHUTDOWN (i.e. possibly with disabled network devices). The work-around is REALLY easy. But as an ubuntu/kernel/network bug, almost impossible to trace.

Maybe this hint (enable Wake-On-Lan if you experience network problems and if you're a double-booter, or try the liveCD from a windows system), could be included in the "known issues" section of the distro???
Whom do I tell?

What to do with this bug now? At least my comments and the one by IKT are probably misfiled, at least I imagine that the sporadic malfunction of a double ethernet setup is due to other problems...

[IKT (ikt)]

Would it be best to file the bug upstream with the kernel team or ?

[Bryan (k1cd)]

I've got a RTL-8138/810x on the mobo with a Core Solo in Ubuntu 9.10 *hp slimline). It starts up and does its thing but then stops working. I can usually do an 'apt-get update' and maybe halfway through a "full-upgrade" before it starts with "host down" errors. Network connection looks normal but is unresponsive either to ping or the network manager trying to disconnect. Still investigating.

[penalvch (penalvch)]

Bradley M. Kuhn, 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? If so, could you please test for this 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 please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

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 text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.
