No response
There's a PR (#6050) that may help with this issue. Similar failures are seen when the device fails to ACK data in time, and the PR changes the mark/space ratio on SCL to give the device longer to respond at any given clock speed.
You can install a trial, beta kernel containing the fix by running sudo rpi-update pulls/6050. Take care to back up any important data in your image before updating in case there is a regression.
