 Trying to find an issue in the dentry cache? Try

 to only enable debugging on the dentry cache.
 
 Red zoning and tracking may realign the slab.  We can just apply sanity checks
 to the dentry cache with
 
-        slub_debug=F,dentry_cache
+        slub_debug=F,dentry
 
 In case you forgot to enable debugging on the kernel command line: It is
 possible to enable debugging manually when the kernel is up. Look at the
