Linux Kernel Configuration
└─>Verbose backtrace
In linux kernel since version 5.2 (release Date: 2019-07-07)  
When the kernel produces a warning or oops, the kernel prints a
trace of the call chain. This option controls whether we include
the numeric addresses or only include the symbolic information.

In most cases, say N here, unless you are intending to debug the
kernel and have access to the kernel binary image.
