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.
