I have found that if I use GENERIC kernel config, I can not trigger this bug, my machine has 64M RAM, default maxusers value in GENERIC kernel config file is 32, this is fine, change it to 128 and recompile/install kernel, I can use fork bomb to crash kernel. so this bug is RAM size and maxusers related.
