Hi James, I have both sticks (v1 and v2) and can confirm your observations. I also pinned the problem down to the commit you specified. I am running on a kernel with that commit reverted for some months now and didn't observe any problems so far. The easiest way to reproduce this issue was to force a complete network scan in tvheadend. With that commit applied, the scan always failed after ~50% of all muxes were scanned. And it was not just about some continuity errors, but a complete loss of signal that could only be resolved by rebooting. After reverting the commit, everything runs fine. Best regards Thomas
