unity-panel-service segfaults 3 to 4 times per second after a fresh install + updates on Lenovo L512

[Jeff Lane ]

I did a fresh install of Alpha 3 and then updated the system this morning to the latest Oneiric updates. I noticed in syslog a number of segfault and GPF messages and thought I should report them :)

System is a Lenovo L512 and this is the 3.0.0.8-generic-pae kernel. I'm not sure if this is causing any issues, the system "seems" stable enough, but seeing segfaults and GPFs is disconcerting.

Thanks for your report.

3 to 4 crash of unity-panel-service per second. Moving to unity.
Is there any crash file in /var/crash ?

[Jeff Lane  (bladernr)]

as a matter of fact, there is... attaching.

[Omer Akram (om26er)]

You don't need to attach the .crash file, double click it and it will take you to launchpad and report a new bug and all the logs will be attached with it. I think this bug should be closed as invalid now as you have the .crash file and you can report a new bug with logs.
