Yesterday I was testing the suspend / wakeup cycle during nearly 2
hours. Currently it is much less frequent and very difficult to
reproduce. I just got one gnome crash at the beginning. I tried to get a
backtrace of gnome-session process crash, but I wasn't able to do it.
This morning I got a wakeup crash again, but I hadn't the debugger
attached. Sorry. (Now I'll try to run it with a debugger attached
whenever I can using a script.)

It has definitely to do with some X input device (uvcvideo, psmouse, usbhid). 
Some more notes:
 * I had ThinkFinger package installed until after upgrade to 11.10. I removed 
it and the system seems more stable.
 * I used GDK_SYNCHRONIZE=1 to see if it makes a difference, that seems not to 
be the case

Regards.
Erny
