kernel driver prevents supend to disk since 3.7 series

[Hermann Lauer]

Hello,
3.7.x kernels prevent my laptop with Optimus VGA from suspend to disk
with an PFIFO write fault in PCOPY0, see kernel log below.

During the 3.6.x upto 3.6.11 suspend worked without problems.
lspci -v info of the VGAs is attached.

What may I do to debug this further ?

Thanks for any help and greetings,
 Hermann

You can try the latest 3.8-rc kernel and if you still won't be able to suspend,
bisecting is the most useful thing you can do (google "git bisect" if you
don't know how).
