<pre>Lakshmi, the dmesg log that I have attached is from drmtip. WHL is on 4.19
kernel. I am seeing sporadic flickers when the fifo underruns occur. It is very
frequent when I use USB-C to USB-C cable to connect external monitor - once in
three tries. Especially, while using the LG monitor on which I am reporting the
issue.</pre>
