I started with commit c40e36... and worked back according to the git
log. The last 'good' build was fb72a0... The next commit breaks it.

What is the next step?
aside: was I using Git bisect incorrectly? Shouldn't it have brought me
here automatically? Using version numbers was a waste of time as ubuntu
was using a yet lower version mumber than was visible when using the
mainline kernel. The commits got me closer to the bad commit.

Resume results in black screen. Graphics can appear completely messed
up (i.e. torn last jpg viewed over top of latest jpg). This happens in
Ubuntu 13.10 and 14.04. It happens with: no intel drivers installed,
and with or without the i915 and intel_agp modules explicitly enabled
in /etc/initramfs-tools/modules.
WORKAROUND: Using the following kernel parameters I no longer get the message
in the log, the video does not appear to be as crisp somehow, but I can suspend
and wake from the command:
linemodeset=0 video.allow_duplicates=1
