Did the patch. The message are gone now. However, i still have
about 50% of cpu power wasted on interupts and i have not idea
what is going on and how to figure out what is geenrated so many
interupts and why. Maybe i should first do CVSup to 5-CURRENT
(i am running 5.2-RC2).

Please, someone comment on this.

Best regards,
