Public bug reported: Random freezes occur up to 3 times per day (8-10 hours). Mouse does not move. Ctrl-Alt-F1 does not switch to terminal 1. SysRq + REISUB does not work, most likely since it's a laptop and it doesn't seem to catch the "Fn" key correctly. A hard reboot is the only solution. The problem appears in Unity, Gnome Classic, XFCE and KDE, but more seldom in KDE (some days not at all). The problem only occurs at two client sites (wifi), never at home (wifi) or the home office (ethernet) which leads me to believe this may actually be network related and not Xorg related. I also get the feeling that it occurs more frequently when running the Opera web browser, but can't be sure. The problem first appeared sometime during the 12.04 release.
Open applications are usually: Virtualbox (2 or 3 instances, winXP and Win7 guests) Firefox Skype Pidgin Tomboy Evolution or Thunderbird Gnome-do Weather indicator etc. I'm fairly technical so I could probably provide further information if told where/how to look.
