Hi, I was trying to install kdb patch to my 2.2.14-12 kernel (kdb_v0.6-2.2.13)and it successfully completed the patching operation but had the following error messages. [root@juhie linux]# patch -p1 < /home/dssp/kdb_v0.6-2.2.13 patching file `Documentation/Configure.help' Hunk #1 succeeded at 10309 with fuzz 2 (offset 358 lines). patching file `Documentation/kdb/kdb.mm' patching file `Documentation/kdb/kdb_bp.man' patching file `Documentation/kdb/kdb_bt.man' patching file `Documentation/kdb/kdb_env.man' patching file `Documentation/kdb/kdb_ll.man' patching file `Documentation/kdb/kdb_md.man' patching file `Documentation/kdb/kdb_rd.man' patching file `Documentation/kdb/kdb_ss.man' patching file `Makefile' Reversed (or previously applied) patch detected!

What are the reasons for the failure? This is the first time I am applying a patch. Please tell me if just compiling the kernel sources and booting the machine from the new kernel will have the kdb enabled.
