Hello to all,
My kernel crashes while booting. I am pasting the log here. I have added debug messages in every function to trace the crash.
Please can you tell me whether the function invocation sequence in my boot process is correct. Also I want to know what is the possible reason for the crash and whether it is related to the serial driver and in what way.
