Console filling with "FireWire GUID 0000000000000000 is invalid!"

Question

Hello all. I would appreciate any help I can get. I know just enough to be a danger to my system.
Im on my 2.4 Ghz Core 2 Duo MacBook Pro. 4 GB mem, OSX 10.7.5. Software is up to date as of yesterday.
Here's the problem. When I wake machine up, within a minute it slows to a crawl, throwing beachballs all over. When it catches up to itself, it still runs slower than normal. Then I can hear the drive being written on, prompting me to check console.I get this message:
8/16/13 12:02:15.000 PM kernel: FireWire GUID 0000000000000000 is invalid!
It repeats every 5 seconds, never ending until a restart.
It DOESN'T happen all the time. VERY intermittent, and haven't been able to recreate it on purpose.
Today, I had an external drive plugged into the firewire 800 port. Normally, I do not.

I received this from Akitio/Thunder Dock Support
"Thank you for your feedback. We are aware of this problem and yes, it happens when the system comes out of sleep mode and the Thunder Dock is connected to your system. It does not affect the functionality of the product but it does tend to fill up the console with error messages.
Unfortunately, we cannot fix this with a simple firmware or driver update and you would have to return the product to us, so that we can replace it.
Thanks for your help
