[ubuntu] 12.04 fails to shutdown after running eclipse

view story

http://ubuntuforums.org – I'm running Ubuntu 12.04 on a Toshiba L670-14L uname -a: Linux iain-L670 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux eclipse Version: 3.7.2 I've tried logging out and shutting down with no improvement, I pressed F7 at shutdown splash and lots of call traces printing but noticed error about cpu. Will run again and post better analysis. Anyone else had this problem? It only seems to happen after running eclipse. (Hardware)
