I was about to suggest that you start by filing a bug against the "mdadm" package (the RAID utilities), since the maintainers of that ought to be best placed to either fix the issue or identify the actual subsystem which isn't behaving. However there looks to be a few entries in https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=mdadm which seem relevant to your situation, e.g. #770002, #714155. If having looked through that list and found the none of them seem to apply to your case then I would suggest filing a bug against that package. Alternatively you might first want to try the debian-users list for more generic user support rather than the ARM specific knowledge of the folks on this list.
Thanks for your comment. A critical bug in mdadm (#784070) seems to exactly discribe my problem ... (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=784070)
