Description (partial)

On the CRS-8 system running 3.6.2 IOS XR release we may see periodic i2c bus hang/unhang error messages

It happens where both active and standby RPa are accessing
external power supply device.  In such cases, one of them would fail
acquiring i2c mastership.  That in term will cause software to output an
i2c error message.
