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, Artem
