I wasn't sure were to post this, but I hope someone had help. I also couldn't find any advice via a Google search.

Every 30 seconds the following line appears in system.log:

*configd[[14]]: FIXME: IOUnserialize has detected a string that is not valid UTF-8, "�SMB012".*

This line appears thousands of times. Any idea what it means and who I fix it?

Thanks,
M.

    I have a similar error coming from powerd and from any program that checks the battery's status (iStat in Dashboard, System Information/Profiler)

     

    3/31/12 1:52:18.076 PM powerd: FIXME: IOUnserialize has detected a string that is not valid UTF-8, "�SMB012".

     

    It seems the battery's serial number is using a non UTF-8 character. This has happened to me with two third-party batteries, but I don't think it's happend with an authentic apple battery. When I take the battery out, the messages stop.

     

    I'm on a 15" 2.2GHz Core 2 Duo MacBook Pro 2007, this has happened with 10.6 through 10.7.3.

     

    I think it might also be causing my mac to crash. Often, it will crash completely (shut off power altogether) immediately after displaying this message.

     

    Also, my mac won't enter safe sleep when the battery reaches a low charge level.
