This is not correct. The advice applies only to enabling debug messages in modules, but how does one enable debug messages kernel image? For example one could want to see debug messages from kernel/module.c which is not in any module, and the kernel parameter would be:

  dyndbg="file kernel/module.c +p"

but grub turns that into

  "dyndbg=file kernel/module.c +p"

which kernel fails to parse.
