I was thinking more about rerunning the same bisect but tell it to assume "crashed: general protection fault in batadv_iv_ogm_queue_add" as OK instead of assuming that it is a crashed like the previous "crashed: WARNING in mark_lock". Just to get a non-bogus bisect result. Or try to rerun the bisect between 40e220b4218b and 89d57dddd7d319ded00415790a0bb3c954b7e386 Kind regards, Sven --nextPart5668474.S8tDUuPlPh Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
