I guess there exist another task who got SIGKILL, and the task entered the endless loop of xino_fread. It may not appear in the log "blocked for more than..." since it is not blocked (loop instead). Such task holds xib_mtx, and it block other processes I think. So I'd suggest you to try the patch for this case too. J. R.
