Comment(by shep):

 Cherry picking 601216e12c65e131453941962f2a8f6e49a2a379  seems to have
 helped reduce much the occurrence of this bug, but it still turned up once
 (after 600+ trouble-free resumes):

 {{{

 }}}

 there were no further error messages, and "rtcwake -m mem -s 60" continued
 to do suspends and resumes, but there was no wake-on-lan happening after
 that and the interface no longer works (cannot ping anything from the XO)
 and the wireless LED is now off.
