HELP: reason of panic?

[Dongman Lee]

Hello, everybody! First of all, I would like to send my thanx to people who
replied to my last query. 
I've got the problem again and I would like to ask your helps. So here goes.
I am  developing the transport protocol on VAX750/4.2BSD. So I put my stuffs to
kernel routines associated with a socket(sendit, recvit, sosend, & soreceive).
And I hacked some programs for this protocol. When I tested new kernel, protocol
worked very well. The painful result happened in a while. The system crashed as
soon as I tried to compile C program(I haven't tried other languages). But this
happened only if I tried it in a user mode. In super user mode, there is no
problem. The error message was "panic: KSP not valid".
How could I get the clue to solve this problem?
Thanx in advance.
