Comment 199 for bug 43961

I have tried uBo's method to remove the module snd-hda-intel (sudo rmmod snd-hda-intel), but unfortunately it doesn't have any effect.
Anyway, how can I see more detailed logs besides the simply "System power off" words after the log daemon has shut down, I want to confirm whether it is a kernel bug or a bug related to my laptop's merchandiser.
