If anyone knows of any other issues that have cropped up wit 3.2.4, please
let me know.

Thanks,

Since mdadm-3.2.4 creating volumes using IMSM containers is impossible (segfaults), unless the kernel is 3.1.x or higher (for instance everything SEEMS to work in RHEL 7.0 Alpha and openSUSE 12.1). Full story from SLES 11 SP2 (kernel-3.0.13-0.27-default) with mdadm-3.2.4 :

$ mdadm --zero-superblock /dev/sd[cd]
$ mdadm -C /dev/md/imsm0 -a md -e imsm -n 2 /dev/sd[cd] -R

    [...]

$ tail /var/log/messages

Similiar story in RHEL 6.3 Beta, those errors don't happen with kernel >= 3.1.x though (or mdadm-3.2.3 :)).
