oe's GDB 7.0 doesn't load symbols for me(csl does)

[GNUtoo]

Hi,
Here's my setup:

htcdream.conf
shr.conf
org.openembedded.dev branch at afc0667965549d0ac1cc5cd93a30c2aa8e47dc28
bitbake gdb-cross

I did the following:
the following 3 devices are implicated:
*1 build laptop
*1 desktop
*1 htcdream
The htcdream is connected to the desktop which is on the same network
than the laptop.

Openssh(not dropbear) is runing on the htcdream.
 
So I do that on the target:
gdbserver 127.0.0.1:8022 Xorg

And that on the desktop:
iptables -t nat -A PREROUTING -p tcp --dport 22 -i wlan0 -j DNAT --to
192.168.0.202:22

And that on the laptop:
# sshfs root@desktop:/ /mnt/NFS
# source
~/oetmp/deploy/addons/arm-oe-linux-gnueabi-shr-htcdream-devshell
# ./arm-oe-linux-gnueabi-gdb
[OE::arm-oe-linux-gnueabi-shr-htcdream]:~$ arm-oe-linux-gnueabi-gdb

done.

Note that codesourcey corrupt the frames but not the oe gdb
so oe's gdb is usable...in assembly...

this will mount / on desktop as /mnt/NFS on your laptop.

the above command seems to be incomplete 

Make sure that you are loading same symbol files in both cases
