Please note that this is a years worth of development. To summarise it would take a bit of time and effort. As you have the code in front of you, it is easier for you to look at the differences in the areas you care about than it is for us to just guess and point out all of the things we can try to remember over that timespan. > 2).

Yes, there have been a number of big bugs fixed in the past year. Search bugzilla.kernel.org and this mailing list archives for details as to many of them. > 3).

Why would your applications not run the same on a new kernel version from an older one? They should still work as the kernel->user interface should not have changed in incompatible ways. Also please note all of the security fixes that have gone into newer kernels. If you release using an old kernel, you will be vulnerable to them. good luck, greg k-h ------------------------------------------------------- Using Tomcat but need to do more?
