Description bwbees0 2014-03-06 16:43:58 UTC

Description of problem:
Kerneloops for no apparent reason.  This has showed up serveral times over the past few days.  A previous recent kernel (I updated about 3 days ago) had issues with wired ethernet connections in that an IP address could be obtained, but no data would move over the wired connection.  While that problem existed, wireless connections worked fine.  The current kernel reported by uname is Linux  3.13.5-200.fc20.x86_64 #1 SMP Mon Feb 24 16:51:35 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux has fixed the wired ethernet problem, but the kerneloops is still occurring, albeit less frequently. Are these issues related? I don't know.  This kerneloops showed up when I logged in before I could do anything else.    
 

Version-Release number of selected component (if applicable):

Linux  3.13.5-200.fc20.x86_64 #1 SMP Mon Feb 24 16:51:35 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
Occurs when logging in.  


Steps to Reproduce:
1. Login
2. abrt notice shows up at bottom of screen 
3.

Actual results:
Usually the system continues to operate, but there have been a couple of instances where the machine rebooted itself. 

Expected results:

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.14.4-200.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.

This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
