We're also seeing this problem on a Dell Inspiron 1100, running Karmic with intel video driver version 2.9.1~git-0ubuntu0tormod from xorg- edgers and a 2.6.31-20 kernel. There are no 3D effects enabled (compiz has been completely removed).
The X server freezes, although the mouse still moves, but the system requires a full reboot. -- [i945g] karmic: INFO: task i915/* blocked for more than 120 seconds. https://bugs.launchpad.net/bugs/451518 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
