working on drive with a kernel panic error

Hello,  I am trying to follow this procedure on a Debian 9 machine that had a kernel panic error and how sort of works, but doesn't shut down properly.  I get this output for the command:

trying to make sense of this part in the procedure:
Step 3.2: Next, run the dracut command:
#dracut -f <initrd-image> <kernal-version>
Any ideas?thanks,Greg---------------------------------------------------
