Here is the progress in tracking this down so far.
I am able to reproduce the problem on following kernel versions.
2.6.18-rc5 2.6.18-rc4 2.6.17.11 2.6.16.28 2.6.15.7 2.6.14.7
I am yet to find a latest kernel version - where this works :( I am going to try older versions of the kernel.
Thanks, Badari
