Mine has done it intermittently along with "RKM 0c: No task request? Probably lost, resending task 1."

I posted about it a while back(https://bitcointalk.org/index.php?topic=626361.msg8284052#msg8284052), but I'm not sure if I mentioned the Chip ID part.  It seemed to happen more on 4.6.0.  I will try to get a screen for you.
