This is not a heisenbug.  It is a reproducible failure to boot on
certain hardware.  It just looks like a heisenbug to the tester
because it doesn't runs the test on the same host each time.

It passes on
  earwig, gall-mite, itch-mite               All of which are Intel machines
It fails on
  leaf-beetle, potato-beetle, woodlouse      All of which are AMD machines

Here is an example of a failure:

The serial log just stops after this:

The test runner's attempt to get debug key output (which start at
19:45:12) didn't succeed.  Results on other machines are similar.
