No, probably not. Do this instead: Boot with "init=/bin/bash" on the kernel command line. You'll probably want to do PATH=/sbin:/bin:/usr/sbin:/usr/bin mount -r /usr first. Then pick any module at all, such as usblp, and do: while : ; do grep Slab: /proc/meminfo modprobe usblp rmmod usblp done and see what you get. The fact that the number keeps going up doesn't mean there is a memory leak.
