Hello Parag - shame on me - it's a very new system, so I don't have a comparable kernel. I've got only a similar, very stable, system running kernel 2.6.18-mm3. I will try out the last stable version from www.kernel.org (2.6.21.3) and give you further information.

Also is it possible for you to try the latest kernel (http://kernel.org/) to see if the problem is still reproducible?
