This has been fixed by Al Viro, 
8dfd588c3180b7403c402b4545164ee4543f8f86, in mainline.

I am now working on kvm and slub intensely disliking each other.

Note: the wiki page is immutable, so I could not update it.

http://lkml.org/lkml/2007/7/18/410

Dunno if it's in latest git.

This thread consisted of two unrelated/different oops stack traces :-)

One of them was fixed by Tejun,
a1da4dfe35bc36c3bc9716d995c85b7983c38a76

The other is SLUB related, I think.

Yes SLAB/SLUB traces.

I will test the SLAB fix ( noone told me is fixed ) and I'll test the
same with SLUB to see whatever is fixed in current git , later.

Here's a new one: 

appledisplay screen blanking driver seems to be broken
It doesn't blank anymore. I haven't done much debugging yet,
but the driver is loaded; just the screen stays on.
Not bisected currently.
