resume after s2disk fails while suspend and resume from memory works.
The system runs the current openSUSE Tumbleweed (20150805) and the VGA controller is a AMD/ATI RV635 Radeon HD 3650. Attached are two displays both via DVI.
First the cards didn't worked at all. Till I got hit by the clue stick to install the xf86-video-ati. I unfortunately only searched for packages with radeon in the name.
https://en.opensuse.org/SDB:Radeon and https://en.opensuse.org/SDB:Radeonhd do not give the hint to install the xf86-video-ati package. In my case it wasn't present as at the initial install non ATI hardware was in use. Resuming with Kernel >= 3.14
Does not this commit fix it?

The patch is from June 2014 and I replaced my graphics cards in May 2015. I am not sure, but I think, I haven't had successful suspend+resume operations with Kernels which had this fix included and with my old Radeon HD 3450 graphics card.
Someone also commented here
https://bugzilla.kernel.org/show_bug.cgi?id=76761#c19
that suspend+resume broke again on Kernel 3.15.
I did some testing and checked which more recent openSUSE kernels are available from the OBS. And already the first one from Kernel:stable (4.1.4-1.ga37e14f-default) solved the described suspend to disk issue seen with this AMD/ATI RV635 Radeon HD 3650 card.
