By the way, it is probably a good idea to boot with "slub_debug=FZP" to make sure that slub debugging is turned on at runtime (unless you're building at kernel with CONFIG_SLUB_DEBUG_ON=y, which I'm sure Fedora doesn't do). The crashes you're seeing definitely look like corruption in the allocator. - R.
