Hello Martin,

I'm adding you in the discussion because you might have an idea on
what's going on with my array which is using DDF metadata.

Hi Francis,
 I think this problem will be fixed by Martin's latest patch set.
The root cause seems to be that safe_mode_delay isn't being set properly
which is the same root cause as the other problem you had.
