Hello,

> On i686 everything is OK. Configs are the same.
> I'm attaching strace - could You help?

this might be linked to that:
https://alioth.debian.org/tracker/index.php?func=detail&aid=301880&group_id=30602&atid=411544

when you say work", can you give a bit of detail (ie doesn't receive events, 
crash (seems not as per your below strace), ...).
I don't see anything special, at first sight, in your strace.

Also, do you use an x68 generated binary, and if so can you try to recompile 
nut and relaunch... just to see.
