Public bug reported:

Binary package hint: xorg

System: 
Ubuntu Karmic 64 bit 
Macbook Pro 4.1 
nvidia 190.42 graphics drivers
Xorg 1:7.4+3ubuntu10

Periodically, my system will completely hang except for mouse usage.
After a 5-10 second delay, the system resumes and shows 80% cpu usage by
Xorg in system monitor.  This happens without any increased window
usage.  I haven't been able to reproduce it on command.
