Dear Ricard,

thanks for your answer.

I agree with you that a fix of the scrubbing mechanism would be better.
Unfortunately, the problem is very hard to reproduce (and debug).

And perhaps it is already solved? My kernel is not the newest. But it is
not possible to change the version because we have some patches (related
to other hardware) which only works with kernel 3.2.

Do you know about some important bug fixes which have something to do
with the "scrubbing" in the last months?

Best
Steffen
