I merged on top of my Linux-v3.8-rc5 GIT branch...

Sedat Dilek (8):
      mei: Fix some more kernel-doc typos in hw-me.c
      kbuild: deb-pkg: Try to determine distribution
      kbuild: deb-pkg: Bump year in debian/copyright file
      kbuild: deb-pkg: Update git repository URL in debian/copyright file
      Merge tag 'next-20130124' of
git://git.kernel.org/.../next/linux-next into Linux-Next-v20130124
      Merge branch 'deb-pkg-fixes' into 3.8.0-rc5-next20130124-1-pmnext-generic
      Merge branch 'Linux-Next-v20130124' into
3.8.0-rc5-next20130124-1-pmnext-generic
      Merge branch 'pm-next' into 3.8.0-rc5-next20130124-1-pmnext-generic

...and this f-u-s the machine as well.
So, the culprit seems not to get from your PM stuff.

Anyway, this does not help me... but hope it's good news for you, Rafael :-)!
