Comment 217 for bug 43961

Sorry, guys. I was too glad that day.
Later when I tried "#sudo rmmod pcmcia", sometimes the laptop could turn off the power, but sometimes it could not.
Anyway, it gives me an option which could increase the "possibility" of shutting down properly.
However, I'm still wondering why shutting down links with "probability". Why sometimes it worked, sometimes it didn't. Weird!
