Please elaborate. Does it mean that this dmesg report message is a false
positive? Or does it mean that this is a known problem (or a mostly harmless
code ugliness) which is going to be fixed?

I had some occasional hangs when trying to reboot or shutdown my PS3. I 
suspect it could be caused by some rare race condition. That's why I'm a
bit suspicious about different things.
