Not sure what is going on. All I know is that KERN_CONT is considered
deprecated and that it should be avoided. From commit 45c55e92fcee 
("checkpatch: warn on logging continuations"):

     pr_cont(...) and printk(KERN_CONT ...) uses should be discouraged
     as their output can be interleaved by multiple logging processes.

Thanks,

Bart.
