Error kernel version!
Just what I thought ;-) Kernel is composed of both Db specific and Db indepedent parts. Infact the the critical binaries like disp+work are part of DB independent part. You need to download both (same release and pATCH) anduncar them in one single location.And then copy the resultant folder contents (contents) over to kernel directory (overwrite exisiting ones/add new binaries if any). Please check the kernel upgrade documentation. Oncethat is done check disp+work at OS level. It should show 720 Extension with the patch applied.
