Due to a full ring buffer, the driver may be unable to send updates to the Hyper-V host. But outputing the error message can make the problem worse because console output is also typically written to the frame buffer. As a result, in some circumstances the error message is output continuously. Break the cycle by rate limiting the error message. Also output the error code for additional diagnosability.
