Hello everybody.
Few minutes ago 2.6.22-rc5 has been
crashed with this error (see also the
bitmap at http://80.204.235.230/foto2.jpg).
Just for record: if I build linux
with 'Debug slab memory allocations'
the box doesn't crash.

The BUG_ON that triggers this signals us that someone tried to perform
a kfree or kmem_cache_free on an object that is not in a slab page.

Hmmm.. That is strange and could point to some sort of race condition.

1. The object is freed. It is the last page on the slab. Thus slab
decommissions the page and resets PageSlab.

2. Another process tries to free the object again. Now the page is no
longer marked as being a SLAB page. Thus the BUG_ON is triggered.

Can you try the same with SLUB? Boot with "slub_debug". If you cannot
trigger the error anymore do limited debugging by booting with
"slub_debug=F". Maybe that will be enough to trigger the race.
