When you see the message 

>  Clozure CL kernel debugger:

it means that CCL has crashed. It's in the low-level interactive debugger, which is used to grovel around in the crashed state to figure out what caused it to crash. It isn't really Lisp anymore when you're in the kernel debugger, and won't be able to interact properly with SLIME.

The solution is going to be figuring what's causing CCL to crash, and the right forum for that discussion is the CCL mailing lists or its Github Issues page here:

Slime-devel probably won't be able to help you much.
