Actually, could you just move the \n to another pr_warning. Because
this can print on console text that makes it look weird too:

login: [    0.191328] **********************************************************
[    0.191493] **   NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE   **
[    0.191586] **                                                      **
