Summary: (net 8139too) dual ethernet system, any reasonable
network causes: NETDEV WATCHDOG: ethN: transmit timed out
Product: Drivers
Version: 2.5
KernelVersion: 2.6.25.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Network
AssignedTo: [email protected]
ReportedBy: [email protected]
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: 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

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

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.

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.

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 ;))

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.)

From: "Alex REDACTED" <[email protected]>

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

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?

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 ;))

I'm absolutely inclinded to do so. What can I do to get you more information, other than the above?
