[PLUG] eee pc error msg on boot

"asus_wmi: Error removing rfkill notify handler /_sb.pcio.pop5
repeat ...pop6
repeat ...pop7

could not write bytes: Broken Pipe"

I have kernel 3.13.0 Ubuntu 12.04

Various function buttons fail to work

Googling gave me lots of very technical stuff that was way beyond my pay grade.

Does anybody here have a clue as to what the issue is, and possibly a
way that a mortal can resolve it?  It is not urgent, as the machine is
still usable.

Thanks,
