Hi
Thanks for you reply , currently we have the default kernel 2.6.18-128.el5
 ( centos 5.3 ) , can i install the kernel-2.6.18-8.1.8.el5.src.rpm and add
the patch to this or do i have to  download the kernel 2.6.21 then compile
it and then install it .  I had been to the kernel.org and cant find the
kernel 2.6.21 , the kernels available are 2.6.27.49 and above .
