Bad packet length error

Hi,
I am running sshd (openssh-2.9p2) on a power-pc LynxOS box, and am
connecting from a ssh client (openssh-2.9p2) on an x86 Linux box.
This works fine for ssh protocol version 1, but am getting the below error
for ssh v2:
Disconnecting: Bad packet length -857542839.
I am also attaching the complete debug traces from sshd & ssh below.
I am not sure if this is an "endian" issue.
Could anyone help me out in debugging this.
Thanks in advance,
Hari
