Hi, Paweł

Are you using a clean 3.6.6 without any modify?

Looks like some threads has set itself to be UNINTERRUPTIBLE with out
any design on switch itself back later(or the time is too long), are you
accidentally using some bad designed module?

BTW, it's better to paste whole log in mail with text style not a picture.
