Debugging Linux Kernel Module with kdb

I patched my kernel with kdb
I built it
I installed it properly always
I added module scull

In console it can be invoked
Break point is set for scull_read with no problems

But it does not prompt at break point


bp scull_read
go

cat > /dev/scull
Hello World

I pressed Ctrl-D

cat /dev/scull
Hello World

No break point is prompted !!!????
I have also tried all this in single user mode
