Hm, interesting. After following the directions above and setting
CONFIG_LD_HEAD_STUB_CATCH=y and then rebuilding, the "should be" address
has changed:

ERROR: start_text address is c000000000000500, should be c000000000000200
ERROR: try to enable LD_HEAD_STUB_CATCH config option

Michael, any ideas?

# CONFIG_MODULES is not set

For this one, I didn't enable CONFIG_EXPERT and LD_HEAD_STUB_CATCH.
I just converted everything possible to be loadable modules
and that resolved the problem.

Michael- do you want any addition(s) to the head_check.sh error
messages, such as:

(a) enable CONFIG_EXPERT and LD_HEAD_STUB_CATCH
(the latter requires the former)
or (b) if CONFIG_MODULES is not enabled, enable it
and change drivers to loadable modules until the ERROR
is resolved.
