debug [KNL] Enable kernel debugging (events log level).
+ debug_boot_weak_hash
+ [KNL] Enable printing [hashed] pointers early in the
+ boot sequence. If enabled, we use a weak hash instead
+ of siphash to hash pointers. Use this option if you are
+ seeing instances of '(___ptrval___)') and need to see a
+ value (hashed pointer) instead. Cryptographically
+ insecure, please do not use on production kernels.
