Actual outcome:
This error appears in dmesg log:

Comment 1 California Sullivan 2015-07-07 20:13:41 UTC 
This appears to have been fixed as of the 0.80 firmware release. I can reproduce the error with firmware versions 0.79 and below, but with firmware version 0.80 and 0.81 (0.81 being the current latest firmware version) the error does not appear.

I am closing this, but it can be reopened should it occur with future firmware releases.
