DRV2605L: Looses I2C communication constantly, cannot be reached

Part Number: DRV2605L

Tool/software:

Hello,

We're going through EVT on our boards, and notice that the DRV constantly looses i2c communication for some reason after a few hours. We have about 10 devices on the bus in total, and it's always the DRV that losses communication. We have no trace to hard reset it, and it's powered by a 3.3v regulator. It never returns until a hard reset.

I found this related thread that was never resolved:
