Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Cause: Some broken user space apps (sometimes binary only) depend on a kernel version for 2.6.x. Consequence: Applications that depend on 2.6.x no longer work. Fix: The preferred fix is to fix the applications, however when this is not possible - eg. with binary apps, you can run the program with a "2.6.x personality" Result: Applications run as expected.
