alternate mdadm to test
I looked at the code again, and "unknown-block()" is exactly what is expected,
so that doesn't tell us anything.
So it is simply an EBUSY problem, meaning a race with mdadm somehow.
Closing the race doesn't seem easy without a lot of code change (which will
happen in the next upstream release, but isn't suitable for openSUSE yet), but
retrying should be just as successful and a lot easier.
So I've modified the code to retry if it gets EBUSY. It only retries 5 times,
but that should be plenty.
Could you please install that attached rpm:
rpm -U mdadm.....
and see if the problem recurs. I suspect we'll have to wait several weeks
before we can be sure it is fixed...
