It did not help :( I had to disable CONFIG_PREEMPT to shut it up.
I had: CONFIG_PREEMPT=y CONFIG_PREEMPT_BKL=y CONFIG_DEBUG_PREEMPT=y
It did what I wrote. Then I had: CONFIG_PREEMPT=y #CONFIG_PREEMPT_BKL=y #CONFIG_DEBUG_PREEMPT=y
and I had the same (or similar messages)
Now I have disabled all the preempt stuff and it is ok. (but not ok with allocation failure, see next mail)
