Bug Description
I have HP Compaq nx7400 (Core 2 Duo, Intel GMA 950 graphics card).
After resume from hibernation every thing seems to work just fine,
but after a few moments strange things begun to happen:
-sometimes the system just hangs;
-sometimes only gnome stops responding (I can switch to console or log in by ssh from another machine);
-sometimes gnome doesn't stop responding but gnome applications like terminal or totem doesn't launch anymore
(surprisingly mplayer or eclipse work just fine, only "native" gnome applications are affected);
-once after resume from hibernation I saw a notification which said about HAL problems (I can't recall exact error);
-usually after resume from hibernation when I try to 'sudo /etc/init.d/gdm restart' everything just hangs,
but once when I tried to 'sudo /etc/init.d/gdm restart', just before system hung I saw this: "[869.11600] BUG: soft lockup detected on CPU#0!";
-sometimes only one gnome applications hangs (when it hung I couldn't launch any other gnome application, but once more mplayer and eclipse worked fine),
last time gnome-gnuchess hung and when I tried to 'killall gnome-gnuchess' it didn't kill it and ps output showed gnome-gnuchess as 'defected' process
Please, could someone give me some instructions what can I do to locate real source of the bug?

Thanks for the report, I'll see if I can help. Firstly, can you check in your /var/crash/ folder for any log files relating to this problem. Also, once its appeared, can you check in the system logs (System > Administration > System Logs) to see if there is anything listed in any of them? If there is, can you attach/upload the log file to this report please?
