Just one note. In future, please do not send logs in format flowed
emails as space on end of line has special meanings. And output is
wrapped randomly and hard to read (like in my quoted text above).

If you are unable to configure email client correctly (turn of format
flowed) then rather attach logs as attachment (ideally marked with
Content-Disposition: inline).

See linux/Documentation/email-clients.txt where are very useful hints
how to fix buggy email clients.
