I currently test the patch "0001-x86-mm-hibernate-Fix-misjudgment-of-nosave-region-to.patch". At first I test it with Kernel 3.12.36. This Kernel worked reliable with BIOS/GPT booting for my system. The original patch didn't apply cleanly. So I refreshed the patch. Until now, hibernate/resume works reliable with this patch and Kernel 3.12.36. I continue testing. Later I will test Kernel 3.18.*.
