I'm wondering if there are
some old version of grub out there which did the "load four sectors"

setting up the stack in an invalid manner.

This concerns me deeply. This is a current version of Grub which
shouldn't have any silly 8K limitations. Yet it appears to have a
similar pathology over the ancient version Xudong just described.

The absolute best would be if we could replicate this in simulation
(Bochs or Qemu); this would make it very simple to debug. Would you be
willing to try to do that?
