I was unable to find mistaken patch by git-bisect (maybe because of my
fault in good\bad marking). And I have not found how can I debug this
problem.
I have added
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_INFO=y
but messages are the same.
What can I do? Or I need to retry bisection with accuracy?
Thanks.
