Could you please apply
http://bazar.conectiva.com.br/~marcelo/patches/v2.4/2.4.7pre9/zoned.patch
on top of 2.4.7 and try to reproduce the problem ?

There are two possibilities:

1) the zoned approach code introduced in 2.4.8pre1 (thats why I asked you
to apply the patch alone on top of 2.4.7).

2) The used-once code also introduced in 2.4.8pre1

It seems the problem only happens when the highmem zone is active, right ?
