May be I am not make myself understood. The uhook is not like kgdb, kprobe or
some other debug tools. As I mentioned in previous mail that we can
run the kernel
ksymbal while kernel is running, not like the kgdb that need some
hardware driver support
(lots of problems occurred when I try kgdb),

uhook is more "soft", it just provide a way that can call kernel
routine or ksymbals Asynchronously.

Easy but efficent. I have used it to develop device drivers, very
nice, and not every platform or board support
kgdb.
