I don't think I can't test it, since it seems to be some hard-to-hit
race condition. It certainly doesn't seem to happen all the time -
today was the first time I've seen it on one of my computers.

But if you forward the actual patch to me (the one I see on lkml seems
to be broken and doesn't compile cleanly because it's assiging a
structure to a pointer), I'll try it out anyway.
