I think that HTML is forbidden. You can switch Gmail to plain text
mode with the "More options" down arrow in the lower right corner of
the composing frame.

Thanks, that will help. The first things to test will be:
 - confirm the issue on mx31pdk with mainline,
 - confirm that reverting commit 41623c91 on top of mainline is
sufficient to fix the issue,
 - test from mainline whether removing the two "_reset" lines in
vectors.S and adding "b reset" or "bl reset" right after "_start:"
(still in vectors.S) fixes the issue or improves things in any way.

No problem. Maybe Helmut will make some progress in the meantime.
