So it seems to be directly related to the mtdblock devices... I wonder how.

If you have time/interest to experiment and compile some code I would be very
interested to know if changing:

	if (posix_memalign((void**)&super, 512,

on line 1291 of super1.c (in the function load_super1) to

	if (posix_memalign((void**)&super, 4096,

made any difference.
i.e. get the source, make this change, compile and install.  Then
revert the change to mdadm.conf and see if it then fails or works.

Thanks,
