Can you guys please take a look at bug#34692?  It seems to be the
same problem.

  https://bugzilla.kernel.org/show_bug.cgi?id=34692

The offending commit seems to be 270dac35c2.  Does reverting it
resolves the problem for you guys too?

- Does not happen with 2.6.38.6

- Happens 100% of cases with 2.6.39-rc7 (connect ac adapter or suspend
  to ram with ac connected and resume with ac disconnected)

- Reverting 270dac35c26433d06a89150c51e75ca0181ca7e4 fixes issue
