I also have the same problem. It is mentionned in the following forum thread: http://www.ubuntuforums.org/showthread.php?t=151829 and http://ubuntuforums.org/showthread.php?t=197741
As said, it occurs mainly at my parent place where I do use Wi-Fi and mainly this is happening when I am on battery. My system information is described in much detailed in both thread (my user name is the same on the forums and on launchpad.) As the person mentionned it above, the CPU soft-lock-up is displayed in the log often around tg3 entries.
