Sorry, my first message was not fully correct. As I tried to bisect
this, I noticed that this warning happens unfortunately not every
boot. And I noticed another strange behavior. If the
same kernel is always booted, the warning happens very seldom. To make
it appear more frequently I booted v3.19-rc2 and
v3.19-rc1-g08b022a9655bf one after another many times. In this case it
happens with probability around 50% during the boot.

my config is attached.
