Hi,
The following dump is seen while booting 4.4 Kernel Image. I am using the custom kernel image from RobertCNelson.
The 4.4 Image comes up even after the below errors in the log. Could I know what does the report mean and how to resolve it.

The following dump is seen while booting 4.4 Kernel Image. I am using the custom kernel image from RobertCNelson.
The 4.4 Image comes up even after the below errors in the log. Could I know what does the report mean and how to resolve it.
