Ramin,
Thanks for the email. I've added linaro-dev to my response.
The demo consisted of two identical PandaBoards with identical SD
cards running the 3D benchmark of 0xbench using software 3D to amplify
compiler and kernel improvements. 0xbench is a benchmarking program we
ship with our Android images from 0xlab. Each build ran the same
Android userspace, 2.3.4, but one was using the 2.6.36 Linux kernel
and GCC 4.4 from the stock AOSP distribution and one was using an
upgraded Linaro 3.0 Linux kernel with Linaro GCC 4.5. We ran the board
in 640x480 mode so that we wouldn't be memory bound.
Users can use and recreate the builds easily. To program the builds visit
2.6.36
https://android-build.linaro.org/builds/~linaro-android/panda-11.05-release/
and
3.0
https://android-build.linaro.org/builds/~linaro-android/panda-11.07-release/
To recreate the builds from scratch visit:

Here's a video of demo running:

(this is running in 720P mode not 640x480)
I'm happy to help you reproduce the demos. Feel free to drop by
#linaro-android on freenode.

Hi Paul,
in attachment the patch to modify the pwrmgmnt script for lava in order
to take into account the new pm-qa scripts.
Let me know if everything is ok or not.
Thanks for your help !

Using linaro-media-create (version
linaro-image-tools_0.4.8-0ubuntu1~lucid1_all) to create an image the
default image size seems to be 2GB if no --image_size is given.
Creating an image (--image_file) with the recent
linaro-n-ubuntu-desktop-tar-20110817-0.tar.gz fails with tons of "No
space left on device" [1] while the hard disk space is still fine
(tested on different PCs).
It seems that the 2GB image file is loop mounted to
/tmp/xxx/root-disc/ and that 2GB is too small for recent Ubuntu
desktop images. The recent linaro-n-ubuntu-desktop
tar-20110817-0.tar.gz is compressed ~490MB while an older one (e.g.
linaro-n-ubuntu desktop-tar-20110628-1.tar.gz) was only ~430MB. With
this creating an image worked fine with the default 2GB image size.
Adding '--image-size 3G' fixes the issue.
What's about increasing the default image size of l-m-c if it's too
small for creating recent images?
Best regards
Dirk

Key Points for wider discussion
=======================
Move to Android 2.3.5 is done and being tested.
Toolchain with OpenMP, loop parallelization support is done and being tested.
ffmpeg with support for H.264 and WebM runs on Linaro Android.
Team Highlights
=======================

Hi Frederik,
Please use the linaro-dev mailing list (copied here) for future
issue reports. I looked at the log and it's indeed odd that this is
happening. Can you reproduce the problem on any of your hosts, and if
so, what OS version is installed on them?

Yup, once 2.3.5 is here (it is now) we'll move on to that.
