As an community person I AGREED with what you pointed out. My main mistake was I subscribed the mailing list with an useless mailID. Now I changed my mail ID. Surely you will get the proper quote in future. In between the mail change, I lost the continuation for this topic and did not get this reply mail to my new mail ID. Simply copy and pasted the last mail from the archive. Obviously I should improve my C language skills. I am using linux kernel 2.6.30.8 on Ubuntu 8.04, Adeos-ipipe-2.6.30.8-x86-2.4-09.patch and Xenomai-2.5.3 -Prakash
