-         Select the size of an alternate printk per-CPU buffer where messages
-         printed from unsafe contexts are temporary stored. One example would
-         be NMI messages, another one - printk recursion. The messages are
-         copied to the main log buffer in a safe context to avoid a deadlock.
-         The value defines the size as a power of 2.
-
-         Those messages are rare and limited. The largest one is when
-         a backtrace is printed. It usually fits into 4KB. Select
-         8KB if you want to be on the safe side.

-                    17 => 128 KB for each CPU
