Forgot to mention, I am using here lvm on top of crypt.

I have compared initrd images with old and new mdadm, 

$ diff -Naur --brief initrd.img-2.6.32-5-686.good.dir initrd.img-2.6.32-5-686.bad.dir/
Files initrd.img-2.6.32-5-686.good.dir//sbin/mdadm and initrd.img-2.6.32-5-686.bad.dir//sbin/mdadm differ
Files initrd.img-2.6.32-5-686.good.dir//scripts/local-top/mdadm and initrd.img-2.6.32-5-686.bad.dir//scripts/local-top/mdadm differ

Seems that only differences are the mdadm binary and
scripts/local-top/mdadm script,

diff -Naur initrd.img-2.6.32-5-686.good.dir/scripts//local-top/mdadm initrd.img-2.6.32-5-686.bad.dir/scripts//local-top/mdadm
