demsg and cat /sys/class/drm/card0/error

Hi all :

1 Only three boards are suffering from “GPU HANG” issue. Another about a dozen boards are all OK for display.
2 Under Ubuntu OS , I follow the information from “dmesg” and get the /sys/class/drm/card0/error. 
Please refer to the /sys/class/drm/card0/error in attached file.
3 Could someone please kindly  help to check whether it is a kernel issue or not ?
