> Kernel 3.13.10 - works normally.

I tried some kernels as well, here are my findings:
It works fine (on first attempt) with the 3.7.10 kernels from openSUSE 12.3.

It still works fine with the 3.11.6 kernel shipped with openSUSE 13.1.
But it fails with the 3.11.10 kernels available in the official update repo.

Anyway, I guess you/we can stop trying different kernel versions now:

This is the commit that causes it:
https://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git/commit/?h=for-next&id=7b7b68bba5ef23734c35ffb0d8d82079ed604d33

I built openSUSE 13.1's 3.11.10 kernel (the latest one that has this problem) _without_ that commit (it was backported by openSUSE), and it works fine now.

Here is the accompanying bug report that lead to this commit:
https://bugzilla.novell.com/show_bug.cgi?id=773058

Not sure how to proceed now.
I think a bug report against the kernel would be in order, as this not only affects udisks.
(as mentioned, mdir and blkid show the same behavior)

I guess I'll start with reporting it to openSUSE, as they are "responsible" for that change.
But this will have to wait until after the weekend.
