Dmesg showing error after booting ACRN 2.2v.


I tried building ACRN version 2.2 on my intel core i7 laptop and I built it(using ubuntu 18.04) successfully but once booted I tried typing dmesg but it is showing as below error

[drm:gen8_de_irq_handler] *ERROR* Fault errors on pipe A: 0x00000080

Could any one help me to resolve this?

The link I followed to build and load ACRN is ""
Below are the some snap shots for the reference.
