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.
