Hi Bjoern, My original thinking is your case the same with another case on kernel upstream: https://bugzilla.kernel.org/show_bug.cgi?id=77571#c24 But, after trace the dmesg from your machine. I found there have a strange thing for the 0x0000000002551000 address looks a E820_RAM type that should not registered to nosave region. Please file a openSUSE bug against this situation. I need more time to trace this thing and may need your help to run some debugging patch. Thanks a lot! Joey Lee On Wed, Jan 07, 2015 at 07:36:53PM +0100, Bjoern Voigt wrote:

My system:
* openSUSE 13.2 * Kernel 3.12.5 (Kernels >= 3.13 do not suspend; this problem is probably causes by "radeon" driver for my ATI Radeon HD 3450 graphics card) * Intel DH55TC mainboard
After looking in the kernel sources (kernel/power/snapshot.c) I found, that there is some issue with "nosave pages". Is there something I can do?
