Description Bradley M. Kuhn 2008-05-11 16:34:25 UTC
Latest working kernel version: Unknown
Earliest failing kernel version: 2.6.24
Distribution: Ubuntu
Hardware Environment: eBox-4852
Software Environment: Standard Ubuntu Hardy install, with self-compiled kernel direct from kernel.org used fakeroot make-kpkg --initrd kernel_image

Problem Description:

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: [ 2242.871816] NETDEV WATCHDOG: eth0: transmit timed out
kernel: [ 2245.885704] eth0: Transmit timeout, status 0d 0000 c07f media 10.
kernel: [ 2245.885704] eth0: Tx queue start entry 7227  dirty entry 7223.
kernel: [ 2245.885704] eth0:  Tx descriptor 0 is 0008003c.
kernel: [ 2245.885704] eth0:  Tx descriptor 1 is 0008003c.
kernel: [ 2245.885704] eth0:  Tx descriptor 2 is 0008003c.
kernel: [ 2245.885704] eth0:  Tx descriptor 3 is 00080042. (queue head)
kernel: [ 2245.885704] eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

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

kernel: [   15.531666] 8139too Fast Ethernet driver 0.9.28
kernel: [   15.532287] ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 10
kernel: [   15.532343] PCI: setting IRQ 10 as level-triggered
kernel: [   15.532352] ACPI: PCI Interrupt 0000:00:08.0[A] -> Link [LNKA] -> GSI 10 (level, low) -> I

kernel: [   15.533338] eth0: RealTek RTL8139 at 0xe800, 44:4d:50:02:e1:cb, IRQ 10
kernel: [   15.533394] eth0:  Identified 8139 chip type 'RTL-8100B/8139D'
kernel: [   15.533817] ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 11
kernel: [   15.533870] PCI: setting IRQ 11 as level-triggered
kernel: [   15.533878] ACPI: PCI Interrupt 0000:00:0b.0[A] -> Link [LNKD] -> GSI 11 (level, low) -> IRQ 11
kernel: [   15.534759] eth1: RealTek RTL8139 at 0xe400, 44:4d:50:43:41:74, IRQ 11
kernel: [   15.534814] eth1:  Identified 8139 chip type 'RTL-8100B/8139D'

Steps to reproduce:

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

Comment 1 Bradley M. Kuhn 2008-05-11 16:52:41 UTC
I forgot to note in the original report that I have tried the following various settings both ways to no imact:

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.

> 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:

I really dont' know where to begin with this, sorry.  It's _probably_ some
platform-related IRQ delivery problem.  But then again it might be
something else :(

It would certainly be valuable to try some older kernels.

I understand.  FWIW, I tried every BIOS change imaginable to make sure it
wasn't some weird BIOS interaction.

> It would certainly be valuable to try some older kernels.

What are you suggestions regarding "how old"?  My plan *was* to install a
2.4 based distribution next, but if there are specific 2.6.x versions you
think are worth trying, I'm happy to give a try.  I'd rather try the
2.6.x's you suggest first, of course.

Sure thing!

I think an early 2.6 would be a good place to start - 2.6.5. 2.6.9, etc.

If that doesn't help then we can probably safely assume that it's
always been busted.  If that kernel works OK then we can drill in more
cloesly, if you're so inclined (which we hope you are ;))
Comment 5 Bradley M. Kuhn 2008-05-13 08:19:56 UTC
Alex (quoted below) must have seen my bug ticket regarding the 8319too
WATCHDOG bug and replied to me privately.  I include his message below
primarily for posterity on the bug ticket and mailing list archives.  He's
confirming 2.6.23 fails in the same way as well on this particular box
with the two 8139too cards in it.

I expect to try the older kernel versions Andrew suggested in the next few
days and will report back when I have.

Meanwhile, I have vague and more-or-less unfounded theory that this bug is
specific to having two of the same style card in the same box.  Would it
be useful, assuming that I can't make an older kernel work, to try seeing
if I can physically unwire one of the ethernet cards to see if the problem
occurs with only one card wired up?  (This may be undoable without
breaking something on this tiny box, but I'm willing to have a go if folks
think it might help.)

Subject: Re: (net 8139too) dual ethernet system, any reasonable network causes: NETDEV
From: "Alex REDACTED" <redacted@example.com>

We're using an ebox 4852/4853 with debian linux kernel 2.6.23.

Today during testing, we found the exact problem that you're reporting -  
NETDEV WATCHDOG timeouts when any reasonable network load is placed on
routing between the ethernet ports.

We're using the 8139too driver too, version 0.9.28.

No solutions yet, we will probably look into it as time permits.

Just thought you might appreciate another kernel version data point.

Cheers,

I had trouble getting 2.6.5 onto the machine with the distribution it
had.  I have installed a different distribution, and now have 2.6.15
running, and it produces the same error.

So, we know the bug was present in 2.6.15.

Now that I have an older distribution, I should be able to try 2.6.5 and
2.6.9 shortly.  Do you expect it will produce substantially different
results from 2.6.15?

I'm absolutely inclinded to do so.  What can I do to get you more
information, other than the above?
Comment 7 Patrick Reeb 2008-06-02 11:59:20 UTC
Maybe some hints...

I'm Running Feroda 8 on an eBox-4853 and encountering the same NETDEV WATCHDOG Issue. All 2.6 Kernels I tried produced the Bug (Fedora Core 2 with standart and yum updated kernel, Fedora 7 and Fedora 8 with Standard and Updated Kernel).

If someone found a fix or workaround (since this Bug Report is Idle since 18 of may) I would be more than happy to try it as nothing I did fixed the issue till now... :o(

However after doing some testing I found out some points that may hopefully help to trace the Bad Guy (I dont mention having tried all noacpi, noirqpoll etc stuff without success):

The number of open connections:
-------------------------------
Altough the bug comes a little sooner with more connections, downloading a single file (eg. linux distribution with http) also triggers the bug after a certain time (usually after 30 to 60, rarelly 100 Mb of Downloaded Single File Data with no other downloads/Browsing active).

Setting eth0 and eth1 to 10 Mbps Full or Half Duplex of 100 Mbps Half Duplex has no effect in resolving the problem.

Tx Queue Len:
-------------
Changing the Tx Queue length has no effect. Setting it to 1 or 100000 has same effect.

Prerequisit for Bug to happen(?):
---------------------------------
The bug (as far I could see) does only happen when both network adapters are used (in my case as a forwarding router/gateway w/ and w/o OpenVPN and Bridge).

I could download big files from and to the box at full Internet speed (1.5 MBps) with no error of any kind, eventually the Hard Drive got full before completion.

Typical Occurence:
------------------
In my case eth0 is connected to Internet Modem/Firewall and eth1 to Network (I also tried connection directly to a computer without a Switch to see if it could be the trigger for the bug, and it did not change anything).

When I download a big file or the doing heavy Web Browsing (eg Reloading constantly a "loaded" web page), after a certain amount of time and Watching both ethX, following events occur:

1-eth0 drops a few packets ~1-5
2-eth0 gets errors and overruns (Nb of errors == Nb of Overruns) 20-50 of these
3-Dropped packets always > Nb Errors == Nb Overruns
4-Eventually eth1 gets screwed too and produces the same events 1 to 3 but with only 5 or 10 Errors/Overruns/Droped


eth0      Link encap:Ethernet  HWaddr 44:4D:50:04:05:AA  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:13820 errors:20 dropped:39 overruns:20 frame:0

          collisions:0 txqueuelen:1000 
          RX bytes:20373389 (19.4 MiB)  TX bytes:816480 (797.3 KiB)
          Interrupt:18 Base address:0x8c00 

eth1      Link encap:Ethernet  HWaddr 44:4D:50:31:20:BA  
          BROADCAST PROMISC MULTICAST  MTU:1500  Metric:1

          Interrupt:19 Base address:0xa800 


When tracing what functions get called (lots of heavy and dirty "printk" in a modified driver) one can notice as expected that when the bug occurs, There is a call to rtl8139_start_xmit for eth1 followed by solely function calls related to eth0. The again 1 or 2 rtl8139_start_xmit for eth1 and eventually NETDEV TIMEOUT resets the hardware after a long time...

BTW the Network Chips used in these eBoxes are 8100B (http://www.wdlsystems.com/downloads/specs/1EBOX48_s.pdf) and no real 8139xxx!!!

If there is something I can do to help, please feel free to ask. I'll try it out whenever I have some time :o)

Some more Infos on the system:
- HD is a Transcend SSD with 2Gb
- Actual Running Kernel 2.6.24.7-92.fc8

I've recently been testing this problem further using the hardware we have.

We have two versions of eboxes: the 4853 and the 4852. The 4853 has the optional wireless LAN card installed.

We previously experienced the routing issue with the 4853, and after a bit of testing, we have discovered that the 4852 does not exhibit this behaviour for us. We have a number of 4852s, but only one 4853. More than one 4852 has worked flawlessly for us.

I tried removing the wlan card from the 4853, and it still exhibited the routing problem, leading me to believe that there must be a hardware or BIOS difference between these two models.

It's also worth noting that our hardware is different from the models listed in the manual I have. Our versions have a single RS232 port instead of a parallel printer port.

Regards,
Alex White.

Hello,
had the same problem with 2 Realtek ethernet cards
(Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C)

Installed today the new Kernel (2.6.26) Problem seems to be solved. 
(I did varios Download/upload tests over 8 hours with no tx timeout)

I also tested if the Problem exists when only 1 Interface is up.
with kernel 2.6.25.10 it worked fine if only 1 of the interfaces is up 
(direct connection with a pppoe modem)

Regards

I had the same problem (same hardware), installing 2.6.26 solved it partially for me. It basicly works now, but throughput is somewhat limited when both interfaces are under load. Throughput when used as a router is somewhere between 25-35 MBit/s, while each interface is capable to transfer the full 100 MBit/s when used alone. CPU Usage is according to "top" not limiting performance, so maybe theres still some bug in the 2.6.26 driver.
Comment 11 Marcel Telka 2008-07-28 06:56:47 UTC
I have eBox-4854. The hardware difference is that eBox-4854 have additional 4 USB ports *instead of* second ethernet port (when compared with eBox-4852/3). So I have only one ethernet port.

The important thing is that I am suffering with the same problem as guys with eBox-4852/3. The problem occurs on my eBox-4854 when I connect something to one of the additional USB ports. When there is nothing connected to the 4 additional USB ports everything works correctly.

I am suspecting that there is something wrong with IRQ routing between the base board of the eBox (the one containing CPU and one ethernet port) and the additional board (the one containing second ethernet port on eBox-4852/3 or additional 4 USB ports on my eBox-4854).

I am running Fedora 8 on my eBox, now with 2.6.25.11-60.fc8 kernel (the latest available, AFAIK).

Just my 2 cents.

I have a similar issue which I have logged as bug 13830 (http://bugzilla.kernel.org/show_bug.cgi?id=13830)

I have the problem with receive packets vanishing - lowering throughput - with just a single inbuilt ethernet device.
Comment 13 jb 2010-04-29 10:50:10 UTC
Maybe some of these problems are connected with via cx700 chipset
and conflicts between 8139, snd-hda-intel, ehci-hcd, uhci-hcd and via agp,
as described in ID 15372?
For this chipset there are also a few acpi errors AE_NOT_FOUND
(not reported yet - I do not know if they are important)

Closing as obsolete, if this is still seen with modern kernels please re-open and update
