Thanks for your reply,

Does that mean just enabling CONFIG_DEBUG_SLAB  in  kernel  config  or
more?

I see:

#define SLAB_POISON             0x00000800UL    /* Poison objects */

in slab.h, but there's nothing settable in there.

Anyway I've recompiled the 2.4.19 kernel with CONFIG_DEBUG_SLAB=y.
Let's see what happens.

Greets,
