Comment(by mmadia):

 following up:
  * Somewhere between 34645 and 34655 is when the KDL started appearing
 with ease.
  * These initial suggestions applied to 34753 resulted in the KDL
 vanishing.
  * A normal 34784 was confirmed to still exhibit the KDL.
  * As per off-list suggestions, tracing_config.h has been modified to
 these non-zero values:
 {{{
 #       define ENABLE_TRACING 1
 #       define MAX_TRACE_SIZE (300 * 1024 * 1024)
 #define SYSCALL_TRACING_IGNORE_KTRACE_OUTPUT    1
 #define VM_CACHE_TRACING                        2
 #define VM_CACHE_TRACING_STACK_TRACE            5
 }}}

 With 3 hours of continually jam -aq @alpha-raw in 34784, no KDL has yet to
 occur.
