Comment 45 for bug 765813

Hi i also have this problem,
syslog and kern.log filling with:
Nov 4 20:32:22 D505 kernel: [ 224.717992] [drm:intel_prepare_page_flip] *ERROR* Prepared flip multiple times

I upgraded the system to
libdrm-intel1 2.4.32-1ubuntu1 2.4.39~precise~ppa2.2
libdrm-nouveau1a 2.4.32-1ubuntu1 2.4.39~precise~ppa2.2
libdrm-radeon1 2.4.32-1ubuntu1 2.4.39~precise~ppa2.2
libgl1-mesa-dri 8.0.4-0ubuntu0.1 9.0.0.99~glasen~ppa1.1
libgl1-mesa-glx 8.0.4-0ubuntu0.1 9.0.0.99~glasen~ppa1.1
libglapi-mesa 8.0.4-0ubuntu0.1 9.0.0.99~glasen~ppa1.1
libxatracker1 8.0.4-0ubuntu0.1 9.0.0.99~glasen~ppa1.1
xserver-xorg-video-radeon 1:6.14.99~git20111219.aacbd629-0ubuntu2 1:6.14.99~really6.14.6~glasen~ppa3
xserver-xorg-video-ati 1:6.14.99~git20111219.aacbd629-0ubuntu2 1:6.14.99~really6.14.6~glasen~ppa3
xserver-xorg-video-nouveau 1:0.0.16+git20111201+b5534a1-1build2 1:1.1.0~glasen~ppa4.1

and after that my openGL stopped working completly with the following error:
glxinfo
name of display: :0.0
X Error of failed request: BadAlloc (insufficient resources for operation)
  Major opcode of failed request: 153 (GLX)
  Minor opcode of failed request: 3 (X_GLXCreateContext)
  Serial number of failed request: 22
  Current serial number in output stream: 25

I have logged this BUG as:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1071530

The only way to get openGL back is to downgrade
libdrm-intel1:i386 (2.4.39~precise~ppa3, 2.4.32-1ubuntu1),
libgl1-mesa-dri:i386 (9.0.0.99~glasen~ppa2, 8.0.4-0ubuntu0.1)

and this produces the first log flood bug...

By the by if you need someone to test a fix i am certainly willing?
Just let me know...
