Summary0016815: r8169 stops working after receiving `NETDEV WATCHDOG: enp2s0 (r8169): transmit queue 0 timed out`
DescriptionI have a Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller built into the motherboard of a GIGABYTE MZGLKAP-00/MZGLKAP-00, BIOS F1 12/21/2017. The network interface works as expected without issue but after random intervals (sometimes days... sometimes only a few hours... but possibly after going `idle`) the kernel will spit out a debug message and then the network interface will become stop transmitting data. It requires a reboot to restore network operations.

I'm running the stock kernel with no external modules.
Steps To ReproduceHave a Realtek network card using the r8169 module
Let the system run 24/7 until the kernel gives a debug message
Additional InformationI found this bug and kernel patch (which the 3.10.0 does not have) that addresses this exact issue. Can we apply this patch?

The afforementioned kernel issue does not seem to be the same issue. It may appear relevant but I have verified that it is not the same.

I have the same issue with the same network chip, after a while running (hours to days) the 'NETDEV WATCHDOG: enp2s0 (r8169): transmit queue 0 timed out' message is logged and after some time* the network card just stops working.

with kernel 3.10.0-957.27.2 this issue is not reproducible, but with 3.10.0-1062 up to the current 3.10.0-1062.9.1 it is. Therefore some patch is responsible for this issue that was committed in between 3.10.0-957.27.2 and 3.10.0-1062. I checked the source code and the diffs and tried to find if the kernel issue patch had been applied and it turns out that that specific patch has already been committed to 3.10.0-957.27.2, so this cannot be a fix. Also, in the kernel issue discussion, it is reported that the Runtime Power Management is responsible and that the issue is caused when the network card is set to 'auto' instead of 'on', but in my system the issue is reproducible and the power/control is set to 'on'. So the issue in my system is not related to that sysfs setting.

Furthermore the specific kernel issue description is the exact opposite of the current centos issue, it first the system has no network activity *until* this kernel warning message appears where the network card works fine afterwards. This issue is about the other way around: network card works fine until this kernel message gets logged and then after some time the card completely stops sending or receiving any packets.

So, I don't have a solution, but at least I excluded a wrong direction that could waste time and effort to continue to pursue.

* minutes to hours. I don't know why, can't figure this out. But the issue always happens *after* this log message.

Can you test-install kernel-ml from ELRepo? As of today, the current kernel version is 5.4.6.el7. This test will show if the issue you are seeing has been fixed in the latest upstream (kernel.org) kernel.

I just found a way to reproduce the issue at will:

setup another system (HOST2) and install iperf3 in both systems and execute the following in HOST1:

iperf3 -s

and then execute in HOST2:

iperf3 -b0 -c HOST1 -u

After 10-15secs the HOST1 will immediately exhibit the issue and all its network traffic will just stop completely. So now I can do quick tests and eventually find what causes this issue. I will also test with the new 5.4.6 kernel too. I'll write up my finding ASAP.

Haven't be able to try the v5.4.6 kernel yet but ...

I can verify that the iperf3 setup does cause the issue as described in the initial report.

And here they are:

- 1062.9.1.el7: ISSUE EXISTS
- 957-27-2.el7: NO ISSUE
- 5.4.6-1.el7: NO ISSUE

So in 5.4.6 kernel, the issue has been fixed. That's good! Now how do we find out what patch fixed it in order to patch 1062.9.1.el7 and backport the fix? I don't want to run the latest kernel on centos 7 for various reasons (I don't trust running latest kernel on old OS env. and I also use modules like ZFS that are compiled against 1062.9.1.el7 etc.)

I comment to inform that I have the same issue. The network interface stops working erratically.
I enclose statistics of our servers that are running different versions of the kernel to confirm the comment of @Nek

I can see that the problem arises in all cases in the onboard network interface.

I also believe that in all cases the device is detected as "Generic Realtek PHY"

Please change the severity of this incident. Many critical systems depend on the proper functioning of the network. This is similar to a system crashing because it requires a reboot to restore normal operation.

CentOS is a rebuild of the sources used to create RHEL. We do not modify anything except to remove branding and logos. You will need to submit your request to Redhat via bugzilla.redhat.com and if/when RH accepts it and incorporates it into RHEL and releases a patched version, then CentOS will pick it up and rebuild it.

First off, the patch referenced in the original report ( https://bugzilla.kernel.org/show_bug.cgi?id=199549 ) is now in the CentOS 7.7 kernel (3.10.0-1062.x.el7).

Second, I'm curious to see which modules are loaded. What is the output from:

lsmod | grep -e ^realtek -e ^r8169 -e ^libphy

Looks like, in the -1062 kernel, realtek is loaded followed by r8169, which should be the correct order. And curiously, there is no realtek module loaded in the -957 kernel.

As TrevorH suggested, please file a report upstream at RH and see what they say.

OK, I built a plus kernel using a patch from:

https://lore.kernel.org/patchwork/patch/1000208/
"r8169: fix network stalls due to missing bit TXCFG_AUTO_FIFO"

Please test the patched plus kernel available here:

https://people.centos.org/toracat/kernel/7/plus/r8168fix/

If this fixes the issue, great. If not, the search will go on.

Forgot to mention that the referenced patch has been in the plus kernel after 3.10.0-1062.12.1.el7.centos.plus. The only way to get this patch into the distro kernel is by way of the upstream (RHEL) kernel.

Perhaps, @jprediger can reopen the RHBZ bug report filed for RHEL (which was closed as a dup of the corresponding Fedora bug) and ask the RHEL kernel get fixed as well.
