I think I might be getting this bug as well. After upgrading to Karmic I get random freezes.
Most often everything but the mouse pointer freezes. Not even caps lock works. Pressing the power button on the computer does not initialize a shutdown as it usually does. When I get the problem I could see the screen flashing black once very rapidly. I have not found any useful info in my syslogs... I'm on the 185 NVidia driver. -- Karmic: frequent freezes https://bugs.launchpad.net/bugs/479296 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
