The "stall" seems to be a dd bug:

strace dd if=/dev/md0 of=/dev/null bs=1048576 count=1024 skip=65536
(...)
open("/dev/md0", O_RDONLY|O_LARGEFILE) = 0
(...)
_llseek(0, 68719476736, 0xbffff2d0, SEEK_SET) = -1 EINVAL (Invalid argument)
read(0, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
1048576) =
1048576
read(0, "\366&\3704\327\310\243\232\332\220\223\235\367\206\300"...,
1048576) =
1048576
read(0, "n\3164\326\366>\330\5\377\236\303>Vf\377f\317<\226\212"...,
1048576) =
1048576
(...)
(reads propably the whole /dev/md0)

...back to investigating the differing md5sums...
