2.3.28: oops :-(

Hi,
during my normal work (playing mp3, grabbing teletext (and copying
teletext data to netware), pinging some important local hosts, running
Netware test server inside vmware), I got following three oops.
First is some problem with kmem_cache_free: slabp was NULL in check
(mm/slab.c:1569):
if (slabp->s_magic != SLAB_MAGIC_ALLOC)
goto bad_slab;
other were deadlocks on &cachep->c_spinlock lock (first in kmem_cache_free,
second in kmem_cache_reap; after that both CPUs died).
As I do not understand current memory allocator, I'm out of ideas.
Maybe I should download Ingo's patches to MM just now. Before these oops
machine was up for almost 24hrs.
