In this case, the base is not added (Adding base addr 0x00000000), kedbg tries to bp on 0x0006B3F0, which is a non valid address and receives an error from the server. There is probably a problem with the linkmap. In my last commit, I added debugging outputs, do you mind retrying with it and post the result ?

thanks,
