Uhhh... Aren't CONFIG_DEBUG_SLAB and CONFIG_DEBUG_PAGEALLOC incompatible
with each other? At least, that's what I was told by none other than
Dave Jones himself (RH Bugzilla #144324, comment #15).

That reminds me, I have one FC3 system here running rawhide kernels, and
it keeps oopsing once every couple of days. Unfortunately I haven't had
a chance to set up a serial console on it again (I'll do that later
today), but I wonder if the combination of DEBUG_SLAB and
DEBUG_PAGEALLOC is why it's oopsing...
