Hi,

I have spent many more hours analyzing this and finally found exactly what 
causes this problem: doing "make prepare" under a running kernel with the 
grsecurity/PAX option CONFIG_PAX_MEMORY_UDEREF set to Yes. I will post this in 
the grsecurity forums as well, it seems to be their bug after all.

cheers,
  Michael
