Thanksalot for quick response Alexander. I did use the same config file mentioned in Linaro AOSP build page. I am now pondering whether to check the AOSP ICS sources used by Linaro...but usb-ethernet speed related stuff shouldnot be affected by anything in framework/userspace.... I use iperf to measure network throughput . Hence again I suspect kernel changes BR Sagar On Oct 5, 2012 10:04 PM, "Alexander Sack" asac@linaro.org wrote:

Hi,
I was using this AOSP ICS build for Panda created by Linaro
http://releases.linaro.org/12.07/android/images/panda-master-gcc44-aosp-stab...
This Linaro AOSP ICS build does not seem to have the usb networking issue (ethernet very slow in AOSP ICS) that I have been trying to fix for few weeks now.
So probably kernel in this AOSP ICS image created by Linaro has some fix
for
it. I checked the pinned-manifest.xml for which kernel it uses <project name="kernel/omap" revision=" 52f476403350050beb0dff135a55c06c9e7a82a9">
So as I understand its above revision checked out from git://android.git.linaro.org/kernel/omap. I tried to download these sources, but I did not find any difference in
the
kernel sources I downloaded from AOSP git. (Both also have seem to have
same
revision!) Also the kernel config file seem to be the same.
I tried to build this kernel and use in AOSP ICS and again I face same usb-ethernet networking issue.
So I am really curious to find the kernel sources used to build the
kernel
in the AOSP ICS images created by Linaro, as I think that the slow
ethernet
issue arises sue to some bug in usb controller in kernel.
Please could you help with some pointers to find these sources? Thanks for your kind support.
what is the pinned manifest should be what is in the build.
Have you double checked that you use the same config?
