Red Hat Bugzilla – Bug 1010104
wired ethernet fails on resume from suspend if switch port activated after resume operation
Last modified: 2015-02-17 12:15:39 EST
Description of problem:
If the switch port gets turned on after the laptop's resumption from suspension, then I find that the only reliable way to get wired networking back again is to shut down and re-boot.
If switch port is on at point of resume, then NetworkManager reliably re-connects to the ethernet.
If switch port is turned on after resumption, then one does not see a link on the wired ethernet (as seen at the switch).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. suspend host
2. turn off ethernet switch
3. resume host
4. turn on ethernet switch
Network Settings tool does not see any wired ethernet device.
Ethernet switch shows no link on the port.
Network Settings should show a wired ethernet device regardless of plug or switch state.
Turning on the ethernet switch (or plugging in the wired ethernet) should activate wired port.
Host is Lenovo G560 laptop, BIOS version 1.33
I have the same problem, Fedora 19 & same driver. A bit of googling around le me to adding a SUSPEND_MODULES line to /etc/pm/config.d/upload_modules as a potential fix but that does not resolve the issue.
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
