Public bug reported:
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?
