Hmm. This "it breaks on real hardware, but works in virtual boxes"
sounds like it might be the DM queue limit issue.

Did the tree you tested with perhaps have commit 8e0ef4128694 (which
came in yesterday through the block merge (merge commit 1ddeeb2a058d
just after 11am Monday), but not the revert (commit bff4b74625fe, six
hours later).

IOW, just how current was that "current"? Your email was sent multiple
hours after the revert happened and was pushed out, but I would not be
surprised if your testing was done with something that was in that
broken window.

So if you merged some *other* tree than one from that six-hour window,
please holler - because there's something else going on and we need to
get the block people on it.
