Hello,
In one of our working system, i2c driver had crashed. This problem occurred when we were doing 4 video calls. Please note as mentioned in dmesg that we are using linux-3.14.26 kernel. We have connected one external RTC clock on this I2C bus. Why such problem may occur? Kindly resolve this problem.
