At this point I'm afraid it's all lost in the mists of time, but the
original patch seems to have come from

http://lists.openfabrics.org/pipermail/general/2006-July/024322.html

looking at the patch, I would guess that the corruption occurred when
the target got an IO request that started at a non-page-aligned address
but that spanned more than one page.

I don't know if the target was ever fixed, or whether that target code
has any relevance today.
