Network breaks in several minutess after upgrade to 3.13.0-53-generic

[Henry Xing]

After upgrade to 3.13.0-53-generic, the PC's network will break in several minutes. Unplug and re-plug in the network cable will recover the network, but will break again later. Reverting to 3.13.0.52 can make network recover and work properly.

This bug has similar symptom with #1456873, and this is created according to Christopher M. Penalver's request.

[penalvch (penalvch)]

Henry Xing, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Hi, Christopher M. Penalver

    To upstream image needs me to uninstall my network card's driver module(r8168). If I do that, I can not verify if it's fixed or not.

[penalvch (penalvch)]

Henry Xing, where did you get the r8168 module from precisely? Was it from a Ubuntu repository, built from source, etc.?

[Henry Xing (alps-xing)]

Christopher M. Penalver, it's from ubuntu repository. Below is the information:

Description-en_CA: dkms source for the r8168 network driver
 r8168 is the Linux device driver released for RealTek RTL8168B/8111B,
 RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D, and RTL8168DP/8111DP,
 and RTK8168E/8111E Gigabit Ethernet controllers with PCI-Express
 interface.
 .
 This driver should only be used for devices not yet supported by the in-
 kernel driver r8169. Please see the README.Debian for instructions how to
 report bugs against r8169 that made it necessary to use r8168-dkms.
 .
 Installation of the r8168-dkms package will disable the in-kernel r8169
 module. To re-enable r8169, the r8168-dkms package must be purged.
 .
 This package provides the dkms source code for the r8168 kernel modules.
 Kernel source or headers are required to compile these modules.

Dilton McGowan II:

    What network driver are you using? The same as rt8168?

[Dilton McGowan II (diltonm)]

Henry Xing,

Back in January 2013 when I got this machine I was on Ubuntu 12. When 14 came out, the upgrade didn't work so hot so I wiped the disk and installed stock Ubuntu 14. So whatever the installer chose is what I'm running. In the 90s I built my own custom kernels but with so many machines over the years I finally just started using default Ubuntu.

I ran "sudo lspci -v" and found that "alx" seems to be my driver:

04:00.0 Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 08)
 Subsystem: Hewlett-Packard Company Device 2ad5
 Flags: bus master, fast devsel, latency 0, IRQ 46
 Memory at f7100000 (64-bit, non-prefetchable) [size=256K]
 I/O ports at d000 [size=128]
 Capabilities: [40] Power Management version 3
 Capabilities: [58] Express Endpoint, MSI 00
 Capabilities: [c0] MSI: Enable+ Count=1/16 Maskable+ 64bit+
 Capabilities: [d8] MSI-X: Enable- Count=16 Masked-
 Capabilities: [100] Advanced Error Reporting
 Capabilities: [180] Device Serial Number ff-f5-7d-8e-4c-72-b9-ff
 Kernel driver in use: alx

Thanks,
Dilton

Henry Xing, could you please perform the requested action in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1457936/comments/4 (which included removing the previously mentioned module) and advise to the results? What this will verify is if the stable upstream branch kernel provides a working driver (necessary data point).

[Henry Xing (alps-xing)]

Hi, Christopher M. Penalver

    I just upgraded my r8168 driver to realtek's latest driver(8.040), which could be downloaded from "http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false". And after this upgrade, my computer ran for nearly 2 hours and hasn't met the network broken problem any more.

    Regarding the r8168's driver in Ubuntu repository is 8.037, I think it needs to be updated in Ubuntu's repository.

    Therefore, I don't think it's necessary to try the upstream kernel any more.

    Please let me know if you have more concerns about this.

    Thanks.

Henry
