Plain old

git-checkout 33f807ba0d9259e7c75c7a2ce8bd2787e5b540c7 seems to dtrt.



git-checkout 33f807ba0d9259e7c75c7a2ce8bd2787e5b540c7

  Fails very very easily.  Basically the machine never successfully boots.


git-checkout 0953864160bdd28dfe45fd46fa462b4d2d53cb96

  Works OK.


So yes, I'd say that the revert was not complete.


aside: running that while loop just slays the machine.  It took 30 seocnds
to respond to ^C (across ssh over the same link).  There's some severe
starvation happening somewhere.
