Has this happened more than once? Anything special to trigger this? Was there an abnormally high load? I can confirm this bug for kernel 3.4.9-1.fc16.i686 It does not appear for 3.4.7 and previous versions. It usually happens after a file open in LibreOffice, Kile, or other applications but there is no obvious scheme that would trigger the bug reliably. The system becomes non-responsive with the cursor being displayed over a full-screen commandline (I think, Gnome is killed) displaying the backtrace as in the previous post with the only difference that the address after 'dereference at', in my case usually is a number above 40. Interestingly, some background tasks such as PulseAudio still continue to run. There is no high load. # Mass update to all open bugs. Kernel 3.6.2-1.fc16 has just been pushed to updates. This update is a significant rebase from the previous version. Please retest with this kernel, and let us know if your problem has been fixed. In the event that you have upgraded to a newer release and the bug you reported is still present, please change the version field to the newest release you have encountered the issue with. Before doing so, please ensure you are testing the latest kernel update in that release and attach any new and relevant information you may have gathered. If you are not the original bug reporter and you still experience this bug, please file a new report, as it is possible that you may be seeing a different problem. (Please don't clone this bug, a fresh bug referencing this bug in the comment is sufficient). (In reply to comment #4) > # Mass update to all open bugs. > > Kernel 3.6.2-1.fc16 has just been pushed to updates. > This update is a significant rebase from the previous version. > > Please retest with this kernel, and let us know if your problem has been > fixed. No more crashes with the new kernel. However, the symptoms disappeared around 2012-09-20 after various updates (in fedora). Due to the unpredictable appearence of the bug, I was not able to pin down the package which caused/fixed the bug. Based on the last comment, closing with resolution of CURRENTRELEASE. |
