HDhomerun tuner fails

See the log below… The HDHomerun locks up. The RPi (running OSMC) fails after just a fw minutes operation. The screen will freeze and audio stops. Once when it failed the audio stopped for a moment, started again then stopped.

I know there is a new version of the HDHR code running. Is anyone else having this problem?

Update: I have found that the display will run properly IF I DISABLE ACCELERATION. This system is running RPi 2 and the GPU memory was set to 256. Increased to 512 but still hangs. Went back to no acceleration. CPU runs (according to TOP) at 300% without hardware acceleration but 30% when acceleration is enabled.

Does anyone have a clue as to what might be wrong?
