It is important that we move this forward for the LT kernels as well, as
the expectation is that if we go pull a image for i.Mx53, Snowball,
Panda etc , the links to the source and dbgsym packages corresponding to
the image should be available at the same location. Is it likely that we
get this support from LT kernels for 11.10?

Title:
  Make available source and debug packages corresponding to Linaro
  binary images

Status in Linaro Ubuntu Evaluation Builds:
  In Progress

Bug description:
  Recently, a user of Linaro images within ARM reported the below:
  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  Some Linaro related questions that I wonder if someone on the alias knows the answers to.

  Yesterday I did this:
  sudo /home/markn/apps/linaro-image-tools/linaro-image-tools-0.4.8/linaro-media-create --rootfs ext3 --mmc /dev/sdb --binary ./linaro-n-ubuntu-desktop-tar-20110629-0.tar.gz --hwpack ./hwpack_linaro-panda_20110629-1_armel_supported.tar.gz --dev panda

  And it all worked splendidly and I have a working Ubuntu on my SDcard.

  But, for various reasons, I now want/need to be able to load the
  matching kernel debug symbols (for vmlinux) into a debugger.

  Initially I thought vmlinux might be pre-built inside the HW pack for
  me. But if it is I can't see it. I can see the kernel used is:
  2.6.38-1003 and I can download the source here https://launchpad.net
  /linux-linaro/+milestone/2.6.39-2011.06

  I could rebuild the kernel, just to get an ELF image with debug
  symbols. But, I'd presumably also need to know the exact version of
  GCC used to build the original on my SD card. (And I don't know where
  to find that info). Or I could rebuild with my current version of GCC
  and also replace the linux binary that linaro-media-create, put on my
  SDcard.

  All this seems a bit contrary to the spirit of Linaro making life
  easy, perhaps my use case isn't typical.

  So my questions are:
  - Does anyone know if the Linaro packages really do contain an image with debug info that I'm just failing to find?
  - If they don't - do we know if they will
  - And finally is there a better way for me to go about this I'm just failing to see?
  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  Similar issues were reported by other Linaro users within ARM related
  to the lack of availability of debug packages. In one instance,
  someone tried a kernel debug of the Linaro images with DS-5 only to
  figure that a matching vmlinux with debug symbols is not supplied.
  This makes life harder for Linaro users.
