I just do a kill(-1,15); It doesn't affect keventd, ksoftirqd_CPUX, etc. as far as i know. Except the khubd, it keeps getting a zombie.

khubd is a kernel thread, yes. But if I issue a 'killall khubd' it shouldn't become a zombie.

I have to admit, I'm really new to the kernel sources. There's still _very_ much I don't know about the kernel. These are the first steps in kernel programming. Sorry if it's the wrong way to do, I just try my best.
