I actually think that the best "test" is to just test the revert and
see if the problems go away.

You may not have found a way to reliably trigger one particular
problem, but apparently you can easily enough trigger some random
issue with enough tests.

If it's some random memory corruption, there may simply not ba a great
reproducer, with the oopses just depending on random layout and
timing.
