OK, thanks.  I guess we can set this problem aside for now, as this bug
isn't present in 2.6.12-rc5 (correct?).

I assume the problem is due to one of the ASLA patches in rc5-mm1, but it's
possible that it lies elsewhere.  It would be great if someone could fire
up quilt and do a binary search...

To summarise, we have three people (one Opteron, one x86, one
unknown-x86_64) reporting this:
