Hi Valdis, Thanks for your reply. I do not want to change kernel.
"do not want to" is very different from "applications can not be ported to newer kernels".
Please realize that the Linux kernel developers have spent the last decade ensuring that you should be able to update to the latest kernel version with no problems or changes needed in your applications. Lots of companies now realize this and have no problem updating to a newer kernel, while running their old applications.
So please don't spread misinformation about how applications will break with new kernel versions, that is almost always not a true statement.
thanks,

Abhishek, I am to agree with Greg KH here. The kernel community does a very good job of not breaking APIs for applications or regressions. Linus also has openly stated he will not accept any patches in the main line kernel tree if they break user space so you should be fine. Further more to be honest I am very impressed with the amount of how little APIs or regressions we get compared to the amount of commits. Abhishek, in addition this seems more like you don't know or are afraid of compiling the kernel over anything else. If you want post lsmod output from your system so I can help teach you how to build the kernel correctly. Nick
If it's a custom board, bringing up new kernel versions can be a quite daunting task that the management of engineering organizations is more often than not loathe to undertake. It can take a lot of education to convince them that the pain and unpredictable development schedule hit of a kernel upgrade is more than compensated for by the increases in stability and features one gets when one goes through the process.
