While I cannot say too much here, I would strongly suggest that you post
more details on how gdbserver actually crashes.  Maybe this rings a bell
for someone.

This makes me nervous.  Non-deterministic behaviour either points to
unstable hardware to test-conditions not fully under control, i.e. some
parameters in the system change that may seem unlinked at first.  I
would try to research here a little bit more - and write a logbook for
yourself of the tests.  Usually this turns out to be worth *a lot* when
new insights can be used to re-classify the old tests and vice versa
those tests can be used to test new insights.
